If an ecosystem depends on pine trees and all of those trees are cut down to build houses, what will probably happen?

North Africa and the Arabian Peninsula have a hot climate with large land masses, which are deserts. Even though, the map of North Africa and the Arabian Peninsula shows large groundwater reservoirs and aquifers. Which of the following answers explains this phenomenon?

• Northern Africa is next to the Mediterranean Sea, which replenishes the underground aquifers. This way, even if the water from the aquifers is being removed faster than rain can replenish them, the amount of groundwater does not decrease.

• Precipitation and humidity are the cause of the aquifers that we see on the map. North Africa and the Arabian Peninsula are in an area where there is a high level of precipitation.

• Humans are constantly using groundwater, which is trapped beneath the ground in aquifers. Due to the hot climate, there isn't much of it available and it does not get replenished, and as a result that causes water stress.

• Aquifers were formed a long time ago by geological processes. The African continent was not always where it is now. In the past it used to be in an area of the world where there was lots of precipitation. That water got trapped beneath the ground between rock layers and moved with the continental plate to where it is now through a geoscience process called the continental drift.

Some copper deposits are found near the Western coast of the Americas. What does the pattern suggest?

• The pattern suggests that copper deposits may be connected to geological activity in the past such as divergent plate boundaries. Copper deposits are formed during earthquake activity.

• The pattern suggests that copper deposits may be connected to geological activity in the past such as convergent plate boundaries. Copper deposits are formed during volcanic activity or during sedimentation processes.

• There is no pattern in the distribution of copper deposits. Copper forms randomly around the world, including the America.

• The pattern suggests that copper can be mined from volcanoes since the Western coast of the Americas is part of the "Ring Of Fire", which has a large concentration of volcanic activity.
