Why would people from Latin America consider emigration as an economic strategy?

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.

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.

Answer:

D. river current exceeds the oceanic current

Explanation:

The bird's foot delta type of deltas occur at places where the river current exceeds the oceanic current. This is the case with the Mississippi River and its delta. The current of the Mississippi River exceeds the currents from the Gulf of Mexico which are very weak. Because the currents of the Gulf of Mexico are very weak, the river is depositing lot of sediments at its final part. The accumulation of this sediment results in splitting up of the river in a triangular manner at its delta, giving it an appearance of the bird's foot, thus the name bird's foot delta.

A "bird's foot" delta configuration develops when the river current surpasses the oceanic current (option D). This is caused by the river's high silt content discharging into oceans with minimal currents and wave action, resulting in delta formations.

A "bird's foot" delta configuration, such as the one displayed by the Mississippi River delta, forms when the river current exceeds the oceanic current, option D. This happens because as a river reaches the ocean or a large lake, the water typically slows dramatically causing any silt in the river water to settle. Rivers with high silt content that discharge into oceans with minimal currents and wave action can build deltas. Deltas are low-elevation areas of sand and mud, formed as the silt settles onto the ocean bottom. Conversely, rivers with low silt content or in areas where ocean currents or wave action is high create estuarine areas, where fresh and salt water mix.

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:

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.

Answer:

The correct option is d) 9 days

Explanation:

First of all the water cycle which is also termed as hydrologic cycle, tells about the continuous movement of water above, below and on the earth's surface.

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.

Answer:

Japan and the Korean Peninsula

Explanation:

The desertification is a process that has become a very big concern in numerous places around the world. With the climate becoming warmer, and with the destruction of the vegetation, this process has become a major environmental concern. Some places though do not have any problem with desertification, like Japan and the Korean Peninsula. In fact, it would be pretty hard to make these two places deserts even if the humans wanted too, and the main reason is that they are under heavy influence of the sea, so they get solid amounts of rainfall and snowfall throughout the year.

Answer:

a. Its consideration of environment impact (such as accommodation for fish) became a model for future dam projects on western rivers

Explanation:

The Columbia River project was a project of great significance for the whole region, especially for the state of Washington. This project had many positive impacts such as production of electricity, irrigation for more than half of the farmlands, development of the area, opening up new jobs. One very big problem though was the impact on the species of fish in the river. As most of them are migratory species, with the building of the dam they were stopped in their movement, thus they became restricted to the upper part of the river. Also, the water and composition of the water changed, and all of these things contributed to significant reduction of the populations of the native species of fish.

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.

Answer:

Set of electromagnetic radiation.

Explanation:

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.

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.

Answer:

d.Consistent color

f.Organic

Explanation:

A mineral is a naturally occurring inorganic element or compound having an orderly internal  structure and a definite chemical composition, crystal form, and physical properties.

Minerals are naturally occuring substances. This implies that they are not synthetic materials that are manufactured in the laboratory.

They are also inorganic element or compound that are not formed through biological processes in living organisms.

The structures of minerals are ordered and internally well arranged.

Compositions of minerals are usually definte but can vary over a narrow range.

Minerals are solids.

The components that are not required in the definition of a mineral include not having chemical variation, having a consistent color, and being organic.

The definition of a mineral does not really include its color, whether it has chemical variation, or if it's organic. In actuality, a mineral is required to be naturally occurring, solid, and have an orderly crystalline structure.

b. Does not have chemical variation is not essential as minerals can indeed have slight chemical variations within a given species. d. Consistent color is likewise not a part of the definition; minerals often come in a variety of colors thanks to impurities in their crystalline structures. Lastly, f. Organic is not required, because minerals are, by definition, inorganic substances.

Answer:

d. Sedimentary rocks are the only rocks that contain fossils.

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.
