D. rift valleys.
Trenches occur at convergent oceanic plates; fossils are extremely old bones, bodies, or footprints, which have gotten so old the intervening years have turned them into rock; U-shaped valleys are valleys which are shaped like the letter U, and are usually formed by glaciers, which tend not to occur underwater very often.
Answer:
C. the movement of the Earth's plates
Explanation:
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.This movement is called plate motion, or tectonic shift.

Answer:
sorry I really don't know the answer
Answer:
TRUE
Explanation:
Cinder cones are usually characterized by the cone-shaped, steep sloping volcanoes, and are typically comprised of pyroclastic materials. These volcanoes have a slope of about 30° to 40° and have a summit at the mouth of the volcano. They are of short height and are found mostly adjacent to the bigger volcanoes such as strato-volcanoes and central vent volcano. They erupt at a much faster rate compared to the long-lived ones.
Thus, the above-given statement is True.
