Question

1. how does heat transfer in the mantle (convection currents) cause tectonic plates to move? 14. if tectonic plates stopped moving, how would earths surface change over millions of years? 15. imagine you are standing near a transform boundary. what natural disaster might you experience, and why? remember: - name the 7 tectonic plates in order

Explanation:

1. Convection currents in the mantle are driven by heat from the Earth's interior. Hot, less - dense material rises, while cooler, denser material sinks, creating a cycle that exerts force on tectonic plates, causing them to move.
2. Tectonic plate movement leads to mountain building, earthquakes, and the formation of new crust at mid - ocean ridges and subduction at trenches. If plates stopped moving, there would be no new mountain formation, fewer earthquakes, and over millions of years, the Earth's surface would become flatter as erosion continued without new uplift.
3. At a transform boundary, two tectonic plates slide past each other horizontally. Earthquakes are the most common natural disaster here as stress builds up and is suddenly released.

Answer:

1. Convection currents in the mantle are driven by heat, causing tectonic plates to move due to the rising and sinking of materials.
2. If tectonic plates stopped moving, over millions of years, there would be less mountain building, fewer earthquakes, and a flatter Earth's surface due to erosion without new uplift.
3. At a transform boundary, earthquakes are the most likely natural disaster as plates slide past each other and stress is released.
