What is meant by equilibrium in geology?

Answer 1

Dynamic equilibrium states that the seismic uplift of an area is balanced by the denudation from that area.

For example, As a landscape is uplifted slopes become larger and steeper, revealing more surface area, this surface area weathers through erosion measures such as freeze thaw; chemical degradation; action of plant roots and mechanical stress. These actions create broken and weathered rock and soil particles.

These particles are removed through denudation force's, such as fluids, air combined with gravity. and returned (generally speaking) to the sea bed ready for sedimentation and then eventually uplift.

This is seen in fluvial geomorphology. As slopes and rivers both act as transport mechanisms for eroded material, and they will adjust there slopes to allow this to happen. Thus if there is more uplift, slopes and rivers will steepen allowing for sediment transport.

Answer 2

In the field of geology, equilibrium is defined as "Isostasy" or a gravitational equilibrium between the earth's lithosphere and its Asthenosphere. When a particular area of the lithosphere reaches Isostasy, it is said to have reached Isostatic Equilibrium. In other words, Isostasy restores equilibrium.

Answer 3

In geology, equilibrium refers to a state in which external forces acting on a geological system are balanced, resulting in a stable or steady condition. It often involves a balance between processes such as erosion, sedimentation, and uplift that shape the Earth's surface over time. An equilibrium state can be transient and subject to change due to shifts in environmental conditions.
