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.

A. producer - clover

   herbivore - bison

   omnivore - prairie dog

   carnivore - black-footed ferret

The temperate grasslands are biomes that are located at the mid-latitudes. The climate is semi-arid, having only seasonal rainfall, and the majority of the year being dry. The landscape is dominated by grasses and flowers. One of the producers in this biome is the clover, which in turn is a food source for the herbivores like the bison. The prairie dig is a very opportunistic eater, and it is omnivore, eating both plants and animals. The black-footed ferret is one of the few predators in this biome, and even though it is small, it is a ferocious predator which feeds exclusively on meat.

B. producer - oak

   herbivore - hair

   omnivore - badger

   carnivore - jackal

The Mediterranean biome can be found on several places around the globe, though it is usually small areas in question, such as the Mediterranean coastline, the southwestern part of Australia, small part of Chile, California, and the Cape area in RSA. This biome is characterized with hot and dry summers, pleasant spring and autumn, and mild, rainy winters. The oak is one of the major producers in this biome. The hair is one of the most common herbivores, while the badger is one of the most prominent omnivores. Both of these species though are often on the menu of the predatory jackal. In general, the animals in this biome tend to be small, or small toward medium size.

C. producer - palm tree

   herbivore - tapir

   omnivore - coati

   carnivore - ocelot

The tropical rainforest is the biome that has the biggest abundance of species, be it plants or animals. It is a biome where it is constantly summer, and where there is very large amounts of precipitation. It can be found at the Equator and in close proximity to it. The palm trees are one of the most common producers in this biome, having high speciation as well. The tapir is one of the largest herbivores, which is also a very dangerous and aggressive animal. A good example of an omnivore is the coati, feeding on anything from small animals, insects, fruits, tubers. The ocelot is a cat that is a predator as all other cats, often hunting on the canopies, with wide range of prey animals on its menu.

D. producer - moss

   herbivore - reindeer

   omnivore - arctic fox

   carnivore - polar bear

The tundra is one of the harshest biomes on the planet. It is covered with ice and snow for most of the year, the temperatures are extremely low, the winds strong, and the summer is very short and mild. The organisms living here have special adaptations to survive in these harsh conditions, such as double layer of fur, wider paws, wider nostrils, larger heart. There are not many producers in the tundra, and the most common is the moss, and that is only in short space of time. The reindeer is one of the largest herbivores in this biome, while the largest land predator is also found in here, the polar bear. The arctic fox is very opportunistic when it comes to food sources, and it eats anything that it can find and digest.

E. producer - pine tree

   herbivore - squirrel

   omnivore - black bear

   carnivore - lynx

The montane forest is a biome found in the higher mountains. This biome has several variations, depending on the elevation. In general, it has mild summers, wet springs and autumns, and snowy, cold winters. One of the most common producers in this biome are the pine trees, which produce lot of food for the herbivorous squirrel. The black bear is the dominant omnivore, eating meat, fish, berries, and everything else that is eatable in order to accumulate fat for the winter. The lynx is one of the top predators in this biome, praying on variety of small and medium sized animals.

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.

Answer:

B) Parabola

Explanation:  The function sunrise can be seen as the function

F( t = day of the year ) = hour of the day when the sun appears.

There are two important days in a year: - 21 of July, the summer solstice, and, -21 of December, the winter solstice.

The 21 of July is the day of the year when the sun appears the earliest, and, the 21 of December is the day of the year when the sun appears the latest.

We measure the sunrise in on year, i.e, 366 days, we begin to measure the 21 of December and end our measurements the 21 of December of the next year. Hence, t=0 corresponds to the 21 of December, t=366 corresponds to the 21 of December of the next year and t_mid=366/2 corresponds to the 21 of July.

It holds that F(0)=F(366) is the minimum of the function and F(t_mid) is the maximum of the function. Between  t=0 and t_mid F(t) is decreasing, also between t_mid  and t=366 F(t) is increasing. Moreover, by the way that the earth travels around the sun, we can assume that F(t) is symmetric with respect to t_mid. Finally, by plotting or drawing F(t), for t between 0 and 366, looks like a parabola facing downwards.

D. synonymous with "craton"

Answer:

the answer is D. synonymous with “craton”

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 electromagnetic spectrum is the energetic distribution of the set of electromagnetic radiation. It consists of electromagnetic waves, which are composed by an electric field and a magnetic field. Every object emits and absorbs these kinds of radiations. This spectrum encompasses from Gamma rays, which are highly energetic electromagnetic waves with high frequency and short wavelength, to Radio waves, which are low energetic electromagnetic waves with low frequency and long wavelength. The visible light, like the sunlight, is only a tiny portion of the electromagnetic spectrum, the rest of the electromagnetic waves are invisible to the human eye, like infrared light, UV light, X-rays, and microwaves, but they can be perceived and be measured with proper filters.

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.
