@ Connexus kid 100% correct
THANKS @connexus kid! YOU GAVE ME A 100%! :)
To get the answers to these questions, you can use your knowledge of Earth's layers and plate tectonics.
1) Where do convection currents happen?
The correct answer is the "mantle." Convection currents occur in the mantle, which is the layer of Earth located between the crust and the core. The movement of molten rock in the mantle creates these convection currents.
2) Which statement is correct about the movement of plates that sit on top of the mantle?
The correct answer is "They regularly move because of the convection currents of magma." Plate movement is caused by the convection currents in the mantle, not in the oceans or connected to Earth's crust or mountains. The convection currents in the mantle move the plates on top.
3) Which statement is correct about the flow of thermal energy inside Earth?
The correct answer is "Energy flow inside the mantle causes magma to rise." The flow of thermal energy inside Earth causes magma to rise. It is the movement of this magma that drives the process of plate tectonics.
4) Which is a result of boundary plates colliding or sliding past each other?
The correct answer is "earthquakes occur." When boundary plates collide or slide past each other, it can create intense pressure and stress, resulting in earthquakes. Valleys can form through a different process like erosion, volcanoes erupt due to plate subduction or hotspot activity, and mountains form when two plates collide.
