Explanation:

These questions relate to Earth's tectonic structure and plate boundaries, key concepts in Earth science. Answers are based on standard geological definitions:

1. The Pacific Plate is the largest tectonic plate.
2. The lithosphere is Earth's outermost cold, rigid layer, made of crust and upper mantle.
3. The asthenosphere lies below the lithosphere and flows like soft plastic; convection currents in it move lithospheric plates.
4. Plate boundaries are where tectonic plates meet. Divergent boundaries form when plates move apart: mid-ocean ridges form at oceanic divergent boundaries, and rift valleys form at continental divergent boundaries. Transform boundaries form when plates slide past each other, causing earthquakes.

Answer:

1. Of all Earth's tectonic plates, the Pacific Plate
2. The cold, rigid rock layer on the outermost part of Earth is the lithosphere. It consists of crust and the top part of the upper mantle
3. Below the lithosphere is the asthenosphere, which flows like soft plastic. Convection currents of lithosphere move because of the asthenosphere.
4. The place where two plates meet is called a(n) plate boundary
5. When two plates move away from each other, a(n) divergent boundary forms.

a. In the ocean, mid-ocean ridges are located at these boundaries.
b. If divergent plate boundaries separate parts of a continent, rift valleys form.

1. When two plates slide by each other, a(n) transform boundary forms. This type of movement causes earthquakes
