Scientists have found evidence that asteroids collided with Earth during its past. What have these impact events been connected to? A. neither global climate changes nor mass extinctions

B. both mass extinctions and global climate changes

C. global climate changes but not mass extinctions

D. mass extinctions but not global clim changes

what's the

so whats the answer

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
