What is the primary force driving the movement of tectonic plates according to plate tactics?
What is the primary force driving the movement of tectonic plates according to plate tactics?
- Thermal convection currents from the Earth's core (correct)
- Gravitational pull from the moon
- Magnetic fields generated by the Earth
- Wind patterns across the surface
How many tectonic plates are theorized to exist on Earth?
How many tectonic plates are theorized to exist on Earth?
- 5 to 10 plates
- 20 to 25 plates
- 10 to 15 plates
- 14 to 21 plates (correct)
What happens to thermal convection currents as they rise from the Earth's core?
What happens to thermal convection currents as they rise from the Earth's core?
- They cool, flow sideways, and then sink (correct)
- They expand infinitely without changing direction
- They evaporate into the atmosphere
- They remain stationary in the mantle

Flashcards
What are tectonic plates?
What are tectonic plates?
The Earth's outer layer is broken into large, moving sections called plates.
What drives plate movement?
What drives plate movement?
Tectonic plates move due to the heat from Earth's core, creating convection currents in the mantle.
What is the asthenosphere?
What is the asthenosphere?
The layer beneath the crust where these convection currents occur.

Study Notes
Plate Tectonics Theory
- Earth's crust is divided into 14 to 21 plates.
- These plates move on convection currents in the asthenosphere.
- Convection currents originate in the Earth's core.
- As hot material rises, it cools and flows sideways before sinking.
- This lateral movement drags the lithosphere (including the tectonic plates).
- This movement creates various types of plate boundaries.
