Las placas tectónicas

The video explains how tectonic plates move due to convection currents caused by heat variations inside the Earth. These movements result in earthquakes, volcanoes, and the formation of mountains. Tectonic plates can move in three ways: separating to form constructive boundaries, colliding to create collision limits or subduction zones, and sliding past each other at conservative boundaries. Each type of movement has distinct geological effects, reshaping the Earth's surface over time.

What natural phenomena are caused by the movement of tectonic plates?

• Tsunamis and cyclones

• Floods and droughts

• Earthquakes and volcanoes

• Hurricanes and tornadoes

What is formed when two tectonic plates move apart?

• A trench

• A fault line

• A constructive boundary

• A mountain range

What happens when an oceanic plate collides with a continental plate?

• The continental plate sinks below the oceanic plate

• The oceanic plate rises above the continental plate

• Both plates remain at the same level

• The oceanic plate subducts beneath the continental plate

Which type of boundary is associated with the creation of mountains?

• Constructive boundary

• Collision boundary

• Conservative boundary

• Destructive boundary

What is a characteristic of a conservative boundary?

• No crust is created or destroyed

• Crust is destroyed

• New crust is formed

• Volcanoes are common
