Answer:
Temperature and pressure
Explanation:
mechanical weathering is the disintegration/breakdown of rocks and this mainly caused the agents of mechanical weathering which are ; water , wind and ice, and this agents of mechanical weathering achieve this due the factors Temperature and pressure.
Temperature : The continuous heating and cooling of rock surfaces cause s wear and tear on the rocks leading to mechanical weathering
pressure : Ice water found in cracks of rocks exert pressure on the rocks and this also causes the rocks to disintegrate overtime
They used maps and are both extremely detailed to perfection
Leo da Vinci did both
The correct answer is letter B. Horizontal water movements. Upwelling is a phenomenon that involves the dense's motion because of the wind. It is cooler and makes the water rich in nutrients towards the ocean surface. The warmer air is replaced and nutrient-depleted surface water are also replaced. This makes increase in plankton population and increase in nutrients at the ocean surface. The movement of the water is vertically up.
