Question

mountain formation
mountains are formed by movements and geographical accidents
erosion
is the process of erosion trans - port and sedimentation of soil
meteors
often small objects collide the earth, asteroids 5 to 10 meters
different geological processes act at different rates, ranging from extremely fast acting on fractions of seconds to minutes to days, to very slow acting over millions to billions of years.
click on the card that represents a fastest process

Explanation:

Mountain formation occurs over long - geological timescales. Erosion also happens over extended periods, though at different rates. Meteor impacts are relatively sudden events compared to the other two, often occurring in fractions of seconds to minutes.

Answer:

Meteors
