Final answer:
The Earth's crust is not 1,000 kilometers thick. The lithosphere, which includes the crust, is about 100 kilometers thick.
Step-by-step explanation:
The statement is False. The Earth's crust is not 1,000 kilometers thick. The crust is relatively thin, with an average thickness of 35 kilometers on land and 5-6 kilometers under the oceans. The lithosphere, on the other hand, is about 100 kilometers thick and includes the crust and the uppermost part of the mantle. So, the lithosphere is thicker than the Earth's crust.
