Heat absorption increases as the albedo decreases. c. Heat absorption increases as the albedo increases. d. Heat absorption decreases as the albedo decreases.
Answer:
Heat absorption increases as the albedo decreases. B
Explanation:
The effects when more ice in the Arctic Ocean melts have on the water is "Heat absorption increases as the albedo decreases"
As more ice melts in the Arctic ocean, the heat absorption of the water increases as the albedo decreases. This means water retains more heat as ices melts.Albedo refers to the segment of the solar energy reflected from the earth surface back into space.Therefore, heat absorption of the water increases as the albedo increases when ice in the Arctic ocean melts.

Answer:
A. Metals can conduct electricity
B. Metals are malleable
D. Copper is an example of a metal
Explanation:
The metals are elements that have strong bonds. All of them are solid at room temperature and require high temperatures that would melt them and turn them into liquid, apart from the mercury, which is the only metal that is liquid on room temperature. Main characteristics of the metals are that they are good conductors of electricity, are malleable, ductile, and lustrous. While some metals are radioactive, the majority of them are not, so we can not put this as a general characteristic of them all. Some of the elements that are metals are copper, iron, nickel, mercury, tin, aluminium, silver, gold, potassium...
Answer:
A.Metals can conduct electricity
B.Metals are malleable.
D.Copper is an example of a metal.
Explanation:
Metals are characterized mainly by being good conductors of heat and electricity (being copper the most known example), by possessing high density and being solid at room temperature (except mercury).
Its properties include malleability, ductility (property of metals to be molded into wires when subjected to tensile stress), toughness and mechanical strength.
what is a scenario that could stop the ocean currents?
The ocean currents are the movement of the ocean waters, with the warm ones moving toward the higher latitudes, and the cold ones moving toward the lower latitudes. In order for the ocean currents to entirely stop, all the water in the oceans should have the same temperature, thus its density will be the same because of it, so there will be no movement in the manner as the ocean currents do. This is highly unlikely to happen though, as this will require all the water to be at the approximately same latitude, as well as to have the same depth, thus to have the same temperature and salinity, and because of it, the same density.
What would be the result in the ocean life if there were a sudden change in thermocline and thermohaline circulation?
If there is a sudden change in the thermocline and thermohaline circulations in the ocean waters, the organisms that live in the ocean waters would suffer badly, and there's a even a high chance of a mass extinction occurring. The reason for such a devastating effect will be that the water temperature will change, the salinity levels will change, and the amount of nutrients and at which depth they will be will change. Since every living organism is adapted to be able to survive in a particular environment, sudden changes in it will put the organisms in a situation where they are not suited to survive in such conditions, so t=they will most probably die out.
Normal faults are ____.
associated with forces that push rocks together
a type of strike-slip fault
associated with anticlines and synclines
produced by shearing tectonic forces
associated with tensional tectonic force
Answer:
Normal faults are associated with tensional tectonic force.
Explanation:
A Fault , in geology represents a planar fracture in a rock , there can be large faults , which are formed by the action of the tectonic forces , even the rapid movement of these tectonic plates on any active fault can lead to an earthquake.
There are two types of fault possible ,
Normal fault and Reverse fault.
In a normal fault , the hanging wall moves in downward direction with respect to the footwall , and , in reverse faults, the footwall moves in downward direction with respect to the hanging wall.
Normal faults are associated with tensional tectonic force and occur when rocks are being pulled apart. They are characterized by a steeply inclined fault plane and a downward movement of the hanging wall.
Explanation:Normal faults are associated with tensional tectonic force. They occur when rocks are being pulled apart, causing one side of the fault to drop down relative to the other side. This type of fault is characterized by a steeply inclined fault plane and a hanging wall that moves downward. Normal faults are common in areas of extension, such as divergent plate boundaries where tectonic forces are pulling the Earth's crust apart.
Examples of normal faults can be found in the East African Rift System and the Basin and Range Province in the western United States. Unlike normal faults, strike-slip faults are associated with shearing tectonic forces and result in horizontal displacement along the fault plane. Anticlines and synclines, on the other hand, are types of folds in rock layers that are typically associated with compressional forces.

Describe the four processes of magma differentiation.
How does the rate of cooling impact crystal size?
Final answer:
The four processes of magma differentiation are intrusion, deep cooling, gradual cooling, and crystal growth. The rate of cooling affects crystal size, with slower cooling allowing for larger crystals and faster cooling resulting in smaller crystals.
Explanation:
The four processes of magma differentiation are:
Intrusion into other rocks while moltenCooling below the earth's surface, generally deepGradual and slow coolingGrowth of individual crystals due to time and spaceThe rate of cooling impacts crystal size. Slower cooling rates allow for larger crystal growth, while faster cooling rates result in smaller crystal sizes. This is because slower cooling gives the crystals more time to grow, while faster cooling restricts their growth.

In Oklahoma, why do injections wells cause earthquakes, and what type of wells are these?
Answer:
Due to fluid flowing down to the fracture
Explanation:
Many scientist and policy maker discovered that depth-volume joint impacts are critical, and the amount of INJECTED MATERIAL becomes more important at point where surface of sedimentary rocks contact crystalline strata rocks and it is capable to cause earthquakes — The main reason behind this massive earthquake is the percolation through deep well which allow easy access to liquid to flow down to fracture that are more susceptible to earthquake.

Answer: seafloor spreading and subduction magmatism
Explanation: Continental crust are termed as the crust destroyed by plate tectonic process mostly.Continental crust usually lies above sea level and because of this existence of land life to evolve from marine life possible.
Seafloor spreading is a type of process in which tectonic plate of Earth's lithosphere separate from one another. Subduction is also a process related with continental crust that occurs when tectonic plates collide with each other rather than getting apart.
The type of plate boundary that currently exists in east Africa where land is spreading is a convergent boundary. True or false?
Answer:
False
Explanation:
The plate boundary that exist in Eastern Africa is a divergent plate boundary. At this boundary, the Somali plate is moving away from the Nubian plate. The Somali plate is smaller, and its boundary is going from the Horn of Africa, through Eastern Africa, down the the southeastern part of the Africa. The Somali plate moves toward the east, thus it is gradually separating from the Nubian plate, forming a continuous rift valley along the boundary, filled with several large lakes at some places. Over time, the two plates will move enough from each other that the ocean waters will fill the space between them, separating them physically, and giving rise to a new continent. It is not clear how much time will be needed for total separation, but the estimates in general are around 10 millions years from now.

Solar brightness and surface temperature generally increase, while oxygen and atmospheric CO2 generally decrease.
The best description of changes in Earth's environment over the past 4 billion years is that solar brightness and surface temperature have generally increased, while oxygen and atmospheric CO2 have generally decreased. This is due to the Sun's fusion reactions, the greenhouse effect, biological activity, and geological processes.
Explanation:The statement that best describes changes in Earth's environment over the past 4 billion years is 'Solar brightness and surface temperature generally increase, while oxygen and atmospheric CO2 generally decrease'. Over Earth's history, the Sun has become brighter as a consequence of its fusion reactions evolving.
Therefore, solar brightness has increased. Simultaneously, the Earth's surface temperature has risen due to the greenhouse effect, combined with increased solar intensity.
On the other side, the amounts of oxygen and atmospheric CO2 have fluctuated considerably, but the significant trend for both has been a generally decreasing concentration. This is primarily due to biological activity and geological processes, like weathering of rocks, which helps sequester carbon dioxide from the atmosphere.

If high tide is at noon, the next high tide will be at… the answer is Midnight
Answer:
Explained
Explanation:
If high tide is at noon, the next high tide would be close to midnight but not exactly at midnight, as it takes about 12 hours and 25 minutes for the next high tide to occur. So if the first high tide happens at the noon then the next high tide might be around 12:25 AM .
Earth rotates 180\degrees in 12 hours, whereas moon rotates only 6\degrees in 12 hrs , which means every coastal area experience a high tide in every 12 hours and 25 minutes or so.
Final answer:
Tides are caused by the gravitational pull of the Moon and are influenced by the position of the Sun. High tide occurs approximately every 12 hours, so if it's high tide at noon, the next high tide will be around midnight.
Explanation:
The question concerns the pattern of the ocean's tides, which are primarily caused by the gravitational pull of the Moon on Earth's oceans. As the Earth rotates, any given point on Earth's surface passes through the two tidal bulges caused by the Moon. Since the Earth rotates once in about 24 hours, and because there are two high tides within that period, this leads to roughly 12 hours between one high tide and the next.
In this case, if high tide occurs at noon, the next high tide would be expected approximately 12 hours later, which would be at midnight. Besides the moon's influence, the sun also plays a role in tidal patterns. During spring tides, which occur when the Earth, Moon, and Sun are aligned, the highest tides happen. Conversely, during neap tides, when the Sun lies at a 90-degree angle to the Earth-Moon alignment, the lowest tides occur.

1. Which type of thunderstorm is the largest in terms of size and area covered? Ordinary Thunderstorm, Mesoscale Convective System (MCS, squall line), or Supercell Thunderstorm If a shelf cloud from an MCS were to pass over you, how does the temperature and wind speed change? What is the most frequent type of damaging severe weather from thunderstorms? Straight Line Winds, 2. 3. Hail, or Tornadoes
1. Mesoscale Convective System
The mesoscale convective system is a very large thunderstorm, or rather system of thunderstorms. This is not a single thunderstorm, but instead it is multiple different thunderstorms that have merged and act as one enormous system. It can occupy space of up to 100 km. These thunderstorms can make all sorts of problems, and because they are combination of different types of thunderstorms, pretty much everything can be expected from them.
2. If a mesoscale convection system is passing over some area, the weather conditions will change rapidly. The first thing that will be noticed is that the wind speed increases more and more, and as the storm peaks, the winds tend to be very strong. The temperatures too change, and they rapidly drop down, bring in much colder weather conditions.
3. straight line winds
The thunderstorms can cause damage in multiple different ways. While some are very devastating, some are not so much, and also, some are much more common, while others are rare. The hail and the tornadoes manage to cause lot of damage, but they are not very common occurrences. On the other hand, with almost every thunderstorm there are straight line winds. These are strong winds that manage to cause damage, be it of smaller or larger scale, depending on what exactly they are influencing.
The Mesoscale Convective System (MCS) is the largest thunderstorm in the area covered. The passing of a shelf cloud from an MCS typically results in a drop in temperature and an increase in wind speed. The most frequent type of damaging severe weather from thunderstorms usually comes in the form of straight-line winds and hail.
Explanation:The largest type of thunderstorm in terms of size and area covered is the Mesoscale Convective System (MCS), also known as a squall line. These weather systems can stretch over hundreds of miles and last for several hours. If a shelf cloud from an MCS were to pass over you, typically the temperature would drop due to the cooler air associated with the storm system. Wind speed usually increases as the storm approaches and is strongest at its arrival.
Regarding the most frequent type of damaging severe weather from thunderstorms, this can vary greatly by location and specific conditions. However, straight-line winds and hail are generally the most common types of damage associated with thunderstorms. Tornadoes, while incredibly damaging, are less frequent overall.

When the side of the earth that faces the moon experiences a high tide, the side of the earth that is opposite from the moon will have a:
•• High tide
•• Low tide
•• Neap tide
•• Diurnal tide
Answer:
When the side of the earth that faces the moon experiences a high tide, the side of the earth that is opposite from the moon will have a high tide.
Explanation:
During the rotation of Earth , moon pulls the Earth , since it is close to Earth .
As moon pulls Earth , it also pulls the water in the oceans , and water can move quite easily and the ocean's water tries to bulge towards the direction of the moon . This process is known as tidal force .
Due to this tidal force , some portion of the ocean will bulge out , and this bulge is referred to as high tide.
High tide occurs on both the side of the Earth facing the Moon and the opposite side, as a result of the Moon's gravitational pull and the inertia of the water.
Explanation:When the side of the Earth that faces the Moon experiences a high tide, the side of the Earth that is opposite from the Moon will also experience a high tide. This is due to the gravitational pull that the Moon exerts on the Earth and the manner in which water reacts to this pull. Essentially, high tides occur on the side of the Earth facing the Moon due to the Moon's gravitational pull, and on the side opposite the Moon because of the inertia of the water.

Children often imitate behaviors seen on television and online videos. This best illustrates the impact of A) modeling. B) latent learning C) instinctive drift D) fixed-interval reinforcement schedules
Answer:
31. C. Law of Effect
32. D. Innate satisfying stimuli
33. A. Modeling
Explanation:
BF Skinner elaborated the Law of Effect of Throndike by introducing reinforcement. Skinner proposed that behavior that is reinforced is more likely to be repeated and without reinforcement, it would eventually die out.
Primary reinforcers are unconditioned, meaning they are biologically important and learning is not necessary. Examples would be eating, sleeping, sex and the like.
The idea of modelling was introduced by Bandura. As children are surrounded by different individuals, exposed to TV characters and the like, they often observe and imitate the behavior of these "models". At first children are more likely to imitate those who are like them, and then evenutally associate the behavior to rewards and consequences. If the behavior they imitated lead to rewards, they would most likely continue the imitated behavior.
B. F. Skinner elaborated what E. L. Thorndike had termed as the Law of Effect. Primary reinforcers would best be described as innately satisfying stimuli, and children imitating behaviors seen on TV or online videos illustrate the impact of modeling.
Explanation:B. F. Skinner's work built upon E. L. Thorndike's theory, often referenced as the Law of Effect. In this theory, actions that are met with rewards or positive outcomes tend to be repeated, while those met with negative outcomes are less likely to be repeated. This is reflected in Skinner's behaviorism theory.
As for the term 'primary reinforcers,' these refer to stimuli that are innately satisfying without the need for learning. It often relates to satisfying basic biological needs such as food or drink.
Finally, kids often mimic actions they see on the TV or online, which is an instance of 'modeling'. This refers to the process of learning by observing and imitating others' behaviors.

solid core, liquid core, mantle, crust
Q6 The uplift of mountains is caused by
endogenic (generated from inside) processes.
aggradation.
denudation.
exogenic (generated from outside) forces.
Q1. igneous
The rocks that form from solidifying magma and lava are the igneous rocks. These rocks are the ones that form first, and later, over the course of millions of years, they gradually transform into metamorphic and sedimentary rocks. The igneous rocks are the hardest rocks, and the formation is closely associated with the intense geological activities, especially the volcanic activities. The igneous rocks that form inside the ground are called intrusive igneous rocks, while the ones that form on the surface are called extrusive igneous rocks.
Q2. the release of seismic energy
The earthquakes are natural occurrences that happens on places where there is internal adjustments in the crust. As the tectonic plates move, they cause lot of pressure on each other, and as they do, the rocks inside the ground break under the immense pressure. As the rocks break, they make gaps inside the crust, which in turn causes the rocks above the gap to fall and fill in the gap. As the rocks adjust themselves, lot of seismic energy is released, and this energy is manifested through very strong vibrations, that tend to move more vertically inside the crust, and horizontally on the surface.
Q3. the uplift of crustal blocks by tectonic forces
The Earth has numerous tectonic plates, and they are not static, but instead are constantly moving and create lot of pressure and energy on each other. This movement is triggered by the convection currents from the mantle layer. One of the products of this constant pressure and energy is the uplifting of crustal blocks. This happens on places where two tectonic plates are colliding or there is a subduction zone. Because of the pressure from bellow, the crustal blocks are pushed upward, resulting in the formations of hills, plateaus, mountains, as well as valleys in between them.
Q4. conical shape
The stratovolcanoes are volcanoes that are characterized by their conical shape. They have steep sides at the upper half, and gentle sloped sides at the lower half, and are the dominant landfrom in the area where they are located, usually sticking out significantly from everything surrounding them. These volcanoes are considered to be the most dangerous, as they have very explosive eruptions, so there's lot of toxins and pyrocalstic material all over the area when they erupt.
Q5. solid core, liquid core, mantle, crust
The Earth is not uniform in its composition, but instead it has several layers. The layers are in order from the center toward the surface in accordance of their composition. In general, we can say that the heaviest elements have sunk toward the center, while the lighter ones have been pushed toward the surface. The deepest layer, thus in the center, is the solid core, made out of metals. Second comes the liquid core, made out of molten metals. Third is the mantle layer, being composed of molten minerals, rocks, as well as having lot of gasses. On the top is the crust, being the thinnest, coolest layer, made out of the lightest elements.
Q6. endogenic (generated from inside) processes
The uplift of mountains happens as a result of the tectonic processes. As the tectonic plates move, some of them move toward each other, creating either a boundary where they collide, or a subduction zone. Both of these types of boundaries cause lot of pressure on the crust, and they push it upward. As the crust is gradually pushed upward, the area starts to gain on elevation, forming mountain ranges over the course of millions of years.

The residence time of atmospheric water means the amount of time water molecule would spend in a reservoir, which is with in the hydrologic cycle.
Usually the residence time in the atmosphere is 9 days, after evaporation and before it starts condensing and falling to the earth in form of percipitation.
What happens to volcanoes as they move away from magma source (plume)?
Answer:
When the crust bearing the volcano moves away from the plume, the volcano becomes extinct
Explanation:
A plume is a warm rock cresting column that arises deep within the mantle, potentially just over the limit of the core mantle. Plume are believed to increase at about 10 times the pace of convection of the mantle. The volcano is active when it is directly above the plume. When the crust bearing the volcano moves away from the plume, the volcano becomes extinct. But the volcanic cone's composition continues.
