Question

which statements about earths crust are true? check all that apply. the crust includes soil, rock, and water. there are three different kinds of crust. the crust is thickest under the ocean. the ocean crust is made of young rocks. the ocean crust is denser than continental crust.

Explanation:

1. Analyze "The crust includes soil, rock, and water": Earth's crust has soil, rock, and water (e.g., ocean water on the crust's surface), so this is true.
2. Analyze "There are three different kinds of crust": There are two main types (oceanic and continental), so this is false.
3. Analyze "The crust is thickest under the ocean": Continental crust is thicker than oceanic crust, so this is false.
4. Analyze "The ocean crust is made of young rocks": Oceanic crust is formed at mid - ocean ridges and is relatively young, so this is true.
5. Analyze "The ocean crust is denser than continental crust": Oceanic crust (made of basalt) is denser than continental crust (made of granite), so this is true.

Answer:

• The crust includes soil, rock, and water.
• The ocean crust is made of young rocks.
• The ocean crust is denser than continental crust.
