Exploring Plate Boundaries and Crustal Features

Mrs. Reese introduces plate tectonics and crustal features, crediting the Crafty Science Teacher. Key vocabulary includes plate tectonics, crust types, and boundary types. The lesson covers Earth's layers, focusing on the asthenosphere, and explains plate movements: convergent, divergent, and transform. Each movement type creates specific land features, such as mountains, trenches, and faults. The lesson concludes with a recap and encourages students to complete their notes and ask questions.

What term describes the layer beneath the Earth's crust that behaves like a plastic?

• Mesosphere

• Troposphere

• Lithosphere

• Asthenosphere

Which type of crust is denser, oceanic crust or continental crust?

• Continental crust

• Oceanic crust

• Both are equally dense

• Density is not related to crust type

What is the primary cause of plate movement according to the lesson?

• Solar radiation

• Gravitational pull

• Magnetic fields

• Convection currents in the mantle
