What are three differences between brittle and plastic strain (may include both characteristics of the strain as well as the conditions and locations where each type of strain occurs), and give an example of the type of structure (deformation feature) associated with each type of strain. Make sure you clearly identify which type of strain is associated with each different trait and feature.

Answers

Answer 1

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.

HOW DOES ALTITUDE AFFECT YOUR BREATHING?

Answers

When you are going towards the mountain, you are requiring more oxygen and it’s more pressure that it affects your breathing.

Answer:

In higher altitudes, the air is usually colder, less dense, and has less oxygen molecules. This means that if you were there, you would need to take more breaths to get the same amount of oxygen as you would at lower altitudes. Higher elevation makes it even harder to breathe.

In case the question gets cut off: which world map below shows the locations of major plate boundaries where most earthquakes and volcanoes occur on earth?

Answers

Answer:

The map labeled with 1 shows the major plate boundaries and where most of the earthquakes and volcanoes occur.

Explanation:

The map labeled with number 1 is showing us the plate boundaries. This can easily be confirmed as the lines that are drawn are in the exact same places where the plate boundaries are located. The plate boundaries are the places that are tectonically the most active on Earth, with earhtquakes and volcanoes being a regular occurrence.

Not all plate boundaries though have around the same intensity of earthquakes or number of volcanoes. This is due to the difference in plate boundaries. At the convergent plate boundaries (depending is it between two continental, continental and oceanic, or two oceanic) there can be the formation of volcanoes or mountain ranges, with earthquake activity varying a lot. At transform boundaries, there isn't volcanic activity but there are a lot of earthquakes. At divergent boundaries, earthquakes are rare, but there is intense and constant volcanic activity.

What do you know about the rock cycle and the three type of rocks?

Answers

Answer:

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material
