Question

Choose the statement(s) that best describe Earth's hydrologic, rock, and tectonic cycles.

They contribute to a balance or equilibrium of Earth's materials.
The cycles are powered by the earth's rotation and orbit.
Old material is disposed of, never to be used again, and new material is created.
They continuously recycle Earth's materials.

Answer 1

The statements that best describe Earth's hydrologic, rock, and tectonic cycles are:

1. They contribute to a balance or equilibrium of Earth's materials.
2. They continuously recycle Earth's materials.

The other two statements are not accurate: the cycles are powered by external sources like the sun (for the hydrologic cycle) and geological processes (for tectonic and rock cycles), and materials are recycled rather than disposed of permanently.
