Answer:
(A) When two oceanic plate moves in the opposite direction, it leads to the formation of new crust and the boundary along which this new crust is formed is known as the Mid-Oceanic ridge. For example Mid-Atlantic ridge.
(B) When an oceanic plate crashes with a continental plate, then the oceanic plate being heavier sinks below the continental plate, producing a subduction zone is created, which is commonly known as the Benioff zone. It is marked by deep trenches and deep-focus earthquakes are generated.
(C) When two continental plates share a divergent plate boundary, if slowly undergoes rifting and with the increasing time, the plates get separated from one another forming a rift valley. For example, the East African rift valley system.
(D) Strike-Slip fault zone is the boundary along which two continental plates slide past one another. Shallow-focus earthquakes are generated in this region. For example, The San Andreas fault.
(E) When two continental plates converges then it forms the sandwich pattern, where high mountain ranges occur. The area undergoes extreme thrusting and folding. for example, The Himalaya.
The answer is D.
The highest amount of immigrants to the US in 1965 consist of Mexicans, basing in Latin America.

Get a life jacket on. Hope you don't die. Try to find land. If you find land and it's close, go for it. If it's far try to send a signal to land. You can use smoke, flags,loud sounds, and flares to send it. Wait until you get help. If no help try to go to an open space in the ship with no objects and take cover.
Answer:
A carbon tax aims to make individuals and firms pay the full social cost of carbon pollution. In theory, the tax will reduce pollution and encourage more environmentally friendly alternatives. However, critics argue a tax on carbon will increase costs for business and reduce levels of investment and economic growth.

The purpose of a carbon tax
The purpose of a carbon tax is to internalise this externality. What this means is that the final price of the good should include the external costs and not just the private cost. It is similar to the ‘polluter pays principle.‘ – which was incorporated into international law at the 1992 Rio Summit. It simply means those who cause environmental costs should be made to pay the full social cost of their actions.

This diagram shows that in a free market (without any tax), we get overconsumption (Q1) of carbon, leading to a welfare loss to society.

Explanation:
Answer:
1. Continental-continental convergence are both <em>continental crust</em> plates.
2. Buoyancy basically means these plates are light float on top of the Asthenosphere.
Explanation:
1. To go a little more into detail, this type of convergence ocurrs when two plates made of continental crust (not oceanic) collide. In the case of ocean-continent convergence, the denser oceanic crust sinks underneath the lighter continental crust.
In this scenario, we have two plates, neither of which want to sink, so instead of going down they just crumple and fold and keep colliding. This collision creates very high mountain ranges such as the Himalaya and usually doesn't contain any volcanic activity because no magma is capable of penetrating through so much crustal material.
2. As for why continental crust is buoyant and doesn't sink has much to do with its composition. Continental crust is made mostly of silicate material. This is very different from oceanic crust which is made of basaltic rocks and is therefore heavier. The term buoyancy refers to the 'floating action' of the continental crust on top of the uppermost mantle.
