Answer:
elastic deformation: the rock returns to its original shape when the stress is removed.
plastic deformation: the rock does not return to its original shape when the stress is removed.
fracture: the rock breaks.
Explanation:
Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.
A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries.
Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries.
When forces are parallel but moving in opposite directions, the stress is called shear (figure 2). Shear stress is the most common stress at transform plate boundaries.
Stress In Earth’s Crust
Enormous slabs of lithosphere move unevenly over the planet’s spherical surface, resulting in earthquakes. This chapter deals with two types of geological activity that occur because of plate tectonics: mountain building and earthquakes. First, we will consider what can happen to rocks when they are exposed to stress.

Answer:
B. Asia and eastern Europe
Explanation:
Geographically speaking, Asia and Europe are actually one continent, Eurasia, as they lie on the same tectonic plate. Because of several human factors though, it has been decided that they are politically split into two separate continents. The reason for the split have been mostly culture, race, and religion.
The majority of the border between Asia and Europe is made out of the Ural Mountains. These mountains are making a border between the eastern part of Europe and the western part of Asia.
Apart from splitting Europe and Asia as separate continents, the Ural Mountains are also splitting the biggest country in the world, Russia, into two separate continents, with the majority being in Asia, and the smaller part being in Europe.
Answer:
Some problems that are caused by the growth of population:
- More population causes a higher demand of food, thereby causing an increase in cultivation by clearing forest land.
- It causes a higher use of resources, that can cause their exhaustion.
- It can cause cases of unemployment.
