Tectonic Plates and Geological Activity

Miss Dupré explains plate boundaries, focusing on convergent boundaries where tectonic plates move toward each other. She describes how continental plates form mountains and how oceanic plates subduct under continental plates, causing geological activity like volcanoes and earthquakes. The lesson highlights the significance of plate boundaries in Earth's geology.

What are the two main layers of Earth's rocky material?

• Hydrosphere and Atmosphere

• Lithosphere and Asthenosphere

• Lithosphere and Hydrosphere

• Asthenosphere and Atmosphere

What is the primary cause of tectonic plates moving?

• Magnetic fields

• Ocean currents

• Wind currents

• Convection currents in the asthenosphere

Where does most geologic activity occur on Earth?

• At the center of tectonic plates

• At the edges of tectonic plates

• In the atmosphere

• In the middle of the ocean

What happens when two continental plates converge?

• They push up to form mountains

• They create a new ocean

• They form a trench

• One plate sinks under the other

Which mountain range is an example of a continental-continental convergent boundary?

• The Andes

• The Rockies

• The Himalayas

• The Alps

What is the process called when an oceanic plate sinks beneath a continental plate?

• Convection

• Divergence

• Erosion

• Subduction

Why are subduction zones considered geologically active?

• They are located in deserts

• They have frequent earthquakes and volcanoes

• They are far from tectonic activity

• They have stable weather patterns

What geological feature is commonly found at subduction zones?

• Plains

• Deserts

• Volcanoes

• Lakes

What can result from earthquakes in subduction zones?

• Tornadoes

• Hurricanes

• Tsunamis

• Droughts

What will the next lesson focus on?

• The impact of weather on tectonic plates

• The history of the Himalayas

• The other two types of plate boundaries

• The formation of deserts
