Wow I’m shocked that’s even a question. Is that for school?
B. Qualitative as they will be writing down the physical description of their observations. Quantitative is numbers, empirical is not correct, and theoretical is guessing.
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:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
Explanation:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
Britain proposed a common policy on Larin America because the Monroe Doctrine satisfied the demands of the British, which kept the French, Dutch and Spanish out of America, as well as sustained trade with them. Furthermore, it allowed the establishing of the "Informal Empire" greatly of South America, where Britain constructed the telephone networks, dominated trade and railways. As a matter of fact, America was in no position to regulate and control the doctrine, but the US Navy was too small, on the other hand, the Royal Navy is the largest navy in the World until 1946, could control it.
