Everything we love depends on this small blue planet, Earth. But how do we study the Earth? In this video, students will be briefly introduced to the basic concepts in geology. Geology is the study of Earth’s physical processes, history, and the processes that act on it. Our planet consists of three layers — crust, mantel, and core. Interaction between these layers form the rock cycle, a gift of nature by which rocks are recycled. The type of rocks that are formed from the cooling of magma or lava are called igneous rocks. Basalt and granite are examples of igneous rocks. Such rock formations can be observed in Big Island of Hawaii and Arizona. Geological studies stem from curiosity, so it is important to stay curious about the natural world.
The video satisfies the 4-ESS1-1 requirement of fourth-grade science proficiency.
Students who demonstrate understanding can: 4-ESS1-1. Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.
