Answer:
The Amazon rainforest in Brazil lost an area about 12 times the size of New York City from August 2018 through July of this year, according to government data released Monday, which shows that deforestation in the biome has shot up significantly since the election of President Jair Bolsonaro.
The 3,769 square miles of forest cover lost during that period represents a 30 percent increase from the previous year and the highest net loss since 2008.
While there are always multiple direct and indirect drivers of deforestation, the largest contributors in Brazil, by far, are cattle ranching, demand for commodities, and logging (Butler, 2019). Cattle ranching is, as it sounds, the issue of large areas of forest being destroyed for cattle farms. This relates to the demand for commodities, as Brazil is the largest exporter of beef in the world (Yale University, 2015). The other largest commodity in the Brazilian Amazon is soybeans. In fact, Brazil is the largest exporter of soybeans in the world (Simoes et al., 2011). Soybeans require large plots of land in order to be farmed, and this land is obtained largely through deforestation. Lastly, logging, the process of obtaining wood for timber and other uses, is a very large contributor to deforestation.

Explanation:
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.
