The answer is C because they show territory gained through the years
<span>C.A floating pile of oil-soaked logs in the Cuyahoga River caught fire, and the resulting media attention led to the first Earth Day.</span>
Answer:
no
Explanation:
a river is a small body of water that is seperated from the "Ocean"
and the ocean is a Big a.s.s thing of water:)
For Earth to make one complete revolution around the Sun takes 365.24 days. This amount of time is the definition of one year.
Effects of Revolution of the Earth: Certain areas are tipped towards, or away from, the sun at different times of the year. This tilting causes the four seasons of the year. The tilting also creates opposite seasons in the Northern and Southern Hemispheres.
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.
