Question

1. earths crust and upper mantle together form the rigid outer layer called the ___.
2. all the water on earth, including oceans, lakes, rivers, and groundwater, makes up the ___.
3. what are the 3 different plate boundaries (movements)? explain how they move and what do they cause.

Explanation:

1. The Earth's crust and upper mantle together form the lithosphere. This is a well - known geological concept.
2. The hydrosphere encompasses all the water on Earth, including oceans, lakes, rivers, and groundwater.
3. The three plate boundaries are divergent, where plates move apart creating new crust; convergent, where plates move towards each other causing subduction or mountain - building; and transform, where plates slide past each other causing earthquakes.

Answer:

1. Lithosphere
2. Hydrosphere
3. Divergent: Plates move apart, creates new crust. Convergent: Plates move towards each other, causes subduction or mountain - building. Transform: Plates slide past each other, causes earthquakes.
