GEOLOGY

Detailed explanation-1: -These rocks collected were as a result of plate tectonics which drifted away.

Detailed explanation-2: -Many of the world’s largest mountain ranges, like the Rocky Mountains and the Himalayan Mountains, were formed by the collision of continents resulting in the upward movement of the earth’s crust (Fig. 7.24 B). The Himalayan Mountains were formed by the collision between Indian and Eurasian tectonic plates.

Detailed explanation-3: -Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift. He is shown here in Greenland.

Detailed explanation-4: -The newest, thinnest crust on Earth is located near the center of mid-ocean ridge-the actual site of seafloor spreading. The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge.

Detailed explanation-5: -Answer and Explanation: The patterns of the ages of the rocks on the seafloor can tell us if the tectonic plates at the seafloor are spreading apart in a divergent boundary. The ages themselves tell us how long the spreading has occurred as well as how quickly the plates are moving apart.
