I know 6 is multiplying by 3 but idk the other ones
Its important to know the source of energy in convection currents because it is what drives the movement of the plates, formation of plate boundaries, and hot spots.
Explanation:
The convection currents are currents that occur in the mantle layer. The prime reason as to why they appear is the difference of heat and pressure between the upper and lower mantle. The energy itself exist because of the core of the Earth, as it is very hot and it has extremely high pressure, so it heavily influences the mantle layer above it.
The importance of understanding the energy source of convection currents is seen in that through it we can understand why we have plate boundaries at some places and not in others, why are spreading zones occurring, and why hot spots occur in the middle of the plates, far away from the boundaries. By understanding these things, we can understand the plate tectonics theory, thus the motion of the plates on Earth's surface.

Two notable ways than setting fishing limits can help protect fish species:
Preservation of fish - this prevents extinction, and at the same time helps other species of fish catch their prey. Thus, making the food chain stable.
Preserves the nature of underwater - fishes tend to take care of their underwater world, and preserving them helps maintain the appearance under the oceans and sea.
Answer:
C. part 3
Explanation:
During part 3 of the cycle, water breaks the rocks apart to form sediments.
Part 3 is the erosion and weathering phase.
- Weathering is the physical disintegration and chemical decomposition of rocks to form soils.
- Water is the main agent of denudation that causes the erosion and weathering of rocks.
- Erosion carries the weathered materials from their site of disintegration.
- These sediments are then transported and deposited to form sedimentary rocks.
