The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust.
Answer:
Landforms are the physical features on the Earth's surface. Mountains, Plateaus and Plains are some major landforms of the Earth
Explanation:
the oldest ocean floor is only 180 million years old, because the oldest crust is destroyed at subduction zones.

What are subduction zones?</h3>
According to NOAA, tectonic plates are fragments of the Earth's hard outer layer that steadily travel across the surface of the globe over millions of years (opens in new tab). (This is a fundamental principle of the theory of plate tectonics, which holds that pieces of the Earth's crust slide across the lower mantle and carry continents with them.) According to the U.S. Geological Survey(opens in new tab), the Earth's crust and the top part of the mantle, a thick, heated layer under the crust, make up that outer layer, also known as the lithosphere (USGS). This lithosphere material curls downward into the heated mantle during subduction zones, when two tectonic plates collide and one slides beneath the other.
