Earth's layers: crust, mantle, core
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to explore earth's layers and crust, mantle, core.
Welcome to Earth Systems and Weather! In this lesson, we'll explore earth's layers: crust, mantle, core. Scientific inquiry allows us to investigate and explain natural phenomena.
The water cycle describes Earth's continuous movement of water. Key processes: Evaporation (liquid water → water vapor, driven by solar energy), Transpiration (water vapor released by plants), Condensation (water vapor cools → liquid droplets, forming clouds), Precipitation (rain, snow, sleet, hail falling to Earth), Runoff and infiltration (water moves across land surface or percolates into groundwater). Earth's atmosphere has layers: Troposphere (0–12 km, weather occurs here), Stratosphere (12–50 km, ozone layer), Mesosphere, Thermosphere, Exosphere. Weather is short-term atmospheric conditions; climate is the average weather pattern over decades. Climate is influenced by latitude, ocean currents, elevation, and proximity to large water bodies. Climate change refers to long-term shifts in global temperature and weather patterns, primarily driven by greenhouse gas emissions.
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.

Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring earth's layers: crust, mantle, core.
