- 15. LITHOSPHERE -crust & upper mantle
- 16. 2 types of crust Oceanic crust is denser than continental crust
- 17. Plate Tectonics is a theory which suggests that Earth’s crust is made up of plates that constantly move and interact in various ways, thus, producing earthquakes, mountains, volcanoes, and other geologic features.

- 20. Plate Tectonics is a theory which suggests that Earth’s crust is made up of plates that constantly move and interact in various ways, thus, producing earthquakes, mountains, volcanoes, and other geologic features. Earth’s crust is broken into large pieces called plates. Each plate is moving slowly but continuously moving. Tectonic Plates are large pieces of the upper few hundred kilometers of Earth that move as a single unit as it floats above the mantle

The crust and a part of the upper mantle make up the ____1____. ____2______ are large pieces of the upper few hundred kilometers of Earth that move as a single unit as it ____3____above the mantle. There are two kinds of crust: ____4____ plates which are thicker but less dense, and Oceanic plates which are thinner but ____5____ . ASSESSMENT

Editor's Notes
- How do you describe the location of earthquake epicenters, active volcanoes, and mountain ranges? They are situated in the same location. Have you ever wondered how this could be possible? Remember that plates are in constant motion. As they interact along their margins, important geologic processes take places, such as the formation of major mountain ranges, active volcanoes, and earthquake epicenters. It means to say that, where there are earthquakes, crusts can either meet or move apart and form mountains and volcanoes.
