Physical geography

At divergent boundaries, tectonic plates move apart. This allows magma to rise from the mantle, creating new crust and often leading to volcanic activity, such as along the Mid-Atlantic Ridge. Convergent boundaries can also have volcanoes, but divergent ones are directly linked to volcanic ridge

Hydrolysis is a chemical weathering process where minerals in rocks (especially silicates) react with water, forming new minerals (like clay) and leading to rock decay. It's most common in warm, wet climates. This is different from mechanical weathering like frost wedging or abrasion.

At divergent boundaries, tectonic plates move apart. This allows magma to rise from the mantle, creating new crust and often leading to volcanic activity, such as along the Mid-Atlantic Ridge. Convergent boundaries can also have volcanoes, but divergent ones are directly linked to volcanic ridges.

After a glacier melts, the weight pressing down on the Earth's crust is removed. The land slowly rebounds or rises, a process known as isostatic adjustment (or isostatic rebound). It’s a key concept in post-glacial geomorphology.

Loess is fine, silt-sized sediment deposited by wind, especially in dry or glacial outwash areas. Over time, it can accumulate into loess plateaus, like those found in northern China or parts of the U.S. Midwest. This contrasts with fluvial (river) or glacial depositional features.
