weathering and erosion Crossword

Type
Crossword
Description

the process of eroding or being eroded by wind, water, or other natural agents erosion
the process of breaking big rocks into little ones. This process usually happens near the surface of the planet mechanical weathering
the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes. chemical weathering
is caused by the repeated freeze-thaw cycle of water in extreme climates. Most rocks have small cracks in them, called joints (or, tectonic joints). When it rains, rainwater seeps into these joints. As the day cools and temperatures at night drop below freezing, the water inside the joints freezes. frost wedging
