CONVECTION IN THE MANTLE

What is the primary effect of convection currents in the Earth's mantle?

• Formation of weather patterns

• Movement of tectonic plates

• Generation of Earth's magnetic field

• Regulation of ocean temperatures

What are the main sources of heat that drive convection currents within the Earth's core?

• Solar radiation and tidal forces

• Radioactive decay and residual/leftover heat from planetary formation

• Chemical reactions and atmospheric friction

• Geothermal vents and volcanic activity

How do the convection currents in the mantle interact with tectonic plates to cause their movement?

• They directly push the plates from below

• They create a dragging force on the overlying plates

• They melt the plates, allowing them to slide

• They generate magnetic fields that pull the plates

Which of these geological phenomena is a direct consequence of tectonic plate movement driven by convection currents?

• Formation of clouds

• Ocean tides

• Earthquakes and volcanic eruptions

• Seasonal weather changes
