Use the graph to describe the effect on temperature as depth increases. a. As depth increases, temperature remains the same.

b. As depth increases, temperature increases.

c. As depth increases, temperature increases then decreases.

d. As depth increases, temperature decreases quickly at first, but eventually becomes constant.

d. As depth increases, temperature decreases quickly at first, but eventually becomes constant.

Explanation:

As seen on the graph above, the temperature decreased quickly as the depth increased. It is seen between 200 meters to 500 meters in depth. The change in temperature is from 26 degrees to 8 degrees, which is an 18-degree difference. After which, the temperature decrease slows down and becomes constant starting at 2,700 meters going deeper to 4,000 meters. The temperature is being maintained at 1 degree.

The other three choices above (a, b, and c) show both an increase in temperature with an increase in depth. This makes the choices incorrect.

not only is it colder, it also becomes darker, less salty, and more dense.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
