Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the best evidence that Earth’s crust has been uplifted?
A
younger fossils above older fossils in layers of rock
B
fossils from marine organisms high on mountain tops
C
fossils of shallow-water fish found at deep ocean depths
D
fossils of marine organisms found in horizontal layers of rocks
Explanation: 

Detailed explanation-1: -Initially there existed a large sea known as the Tethys Sea, and plate tectonic movement led to the rising of the mountains of the Himalayan region, and this was proved by the occurrence of sea animal fossils in the mountains.

Detailed explanation-2: -marine life found at high elevation above sea level b. b. younger fossils above older.

Detailed explanation-3: -Which of these provides the best evidence that Earth’s crust is divided into tectonic plates? The theory that the lithosphere is divided into tectonic plates that move around on top of the asthenosphere.

Detailed explanation-4: -The most abundant rocks in the crust are igneous, which are formed by the cooling of magma. Earth’s crust is rich in igneous rocks such as granite and basalt.

Detailed explanation-5: -Uplift is the process by which the earth’s surface slowly rises either due to increasing upward force applied from below or decreasing downward force (weight) from above. During uplift, land, as well as the sea floor, rises. The outer shell of the earth, the crust, divides into moving sections called plates.
