According to scientists, what are the two main sources of water on the Earth? Choose TWO answers

Rain

Explanation: Rain is the most prevalent way for the Earth to receive water. Rain is, in fact, an active component of the world's water cycle.

When the water on the earth and in the oceans evaporates owing to the heat of the Sun, clouds form, and clouds produce rain.

Rainwater is directly or indirectly used by all water bodies on the planet, including oceans, seas, lakes, rivers, aquifers, groundwater, tubewells, and streams.

Rain is the world's most abundant source of water.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
