Question

eruptions the deep rock material is sub - jected to very high pressures and temperatures and_ movement of rivers and oceans the constant flow of water transforms the surrounding environment_ crystallization during the cooling process of magma, crystallization begins as a consequence of the decrease in temperature 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 slowest process

Explanation:

Eruptions can be quite rapid events. Movement of rivers and oceans is a continuous but relatively faster - changing process in geological terms. Crystallization of magma during cooling is a slow process that occurs over long periods as magma cools deep underground or on the surface over extended time frames, often taking years to geological epochs.

Answer:

Crystallization
