Mantle convection is an important method of heat transport within the Earth. Mantle convection is the driving mechanism for plate tectonics, which is the process ultimately responsible for producing earthquakes, mountain ranges, and volcanos on Earth.
Answer:
Events which occur in chemical reactions like photosynthesis are extremely fast.
Explanation:
To see what happens in reactions such as photosynthesis, scientists need advanced cameras that can capture ultra-fast motions occurring within extremely short scales of time.
