Options

A. Seismic plate
B. Tectonic plate
C. Oceanic plate
D. Fault wave

Answer

**Step-by-Step Solution:**

1. **Understanding the Earth's Structure**: The Earth is composed of several layers, including the crust, mantle, outer core, and inner core. The lithosphere is the outermost layer of the Earth.

2. **Defining the Lithosphere**: The lithosphere includes the crust and the upper part of the mantle. It is rigid and divided into several large and small sections.

3. **Identifying the Plates**: These sections are known as tectonic plates. They float on the semi-fluid asthenosphere beneath them and are responsible for various geological activities.

4. **Filling in the Blank**: The question asks for what the lithosphere is made up of. The correct term to fill in the blank is "tectonic plates."

**Final Answer**: The Earth's lithosphere is made up of a number of small and large plates of **tectonic plates**.
