Earth’s Interior Webquest Answer Key
Earth’s Interior Structure and Composition
Earth’s interior is divided into three main layers: the crust, mantle, and core. The crust is the outermost layer, composed of solid rock and minerals. The mantle lies beneath the crust and is made up of dense, semi-solid rock. The core, located at the center of Earth, is composed of iron and nickel and is extremely hot and dense.
Layers of Earth’s Interior
- Crust: The crust is the thinnest layer, ranging from 5 to 70 kilometers thick. It is composed of various types of rock, including continental crust (found on land) and oceanic crust (found under the oceans).
- Mantle: The mantle is the thickest layer, extending from the crust to a depth of about 2,900 kilometers. It is composed of solid rock that is under immense heat and pressure, causing it to flow slowly.
- Core: The core is the innermost layer and is divided into two parts: the outer core and the inner core. The outer core is liquid and surrounds the solid inner core, which is composed of solid iron.
Methods for Studying Earth’s Interior
- Seismic waves: Seismic waves are vibrations that travel through Earth’s layers. By studying the behavior of these waves, scientists can infer the structure and composition of the interior.
- Drilling: Scientists can drill boreholes into Earth’s crust to collect samples and study the rock formations.
- Gravity and magnetic field measurements: Gravity and magnetic field measurements can provide information about the density and composition of Earth’s interior.
