6th-grade cosplayer is correct 2022
it works for 2023! thank you 6th grade cosplayer!
whats the answers
pls say something
U-shaped valleys provide evidence of glacial erosion.
To get the answer to this question, you would need to understand what U-shaped valleys are and the processes that can form them. A U-shaped valley is a characteristic landform created by the erosive action of glaciers. Glaciers are huge masses of ice that move slowly down a mountain valley due to their own weight. As the glacier moves, it scours and plucks the rock, forming a wide, deep, and U-shaped valley.
By knowing the definition and characteristics of U-shaped valleys, you can determine that the correct process that creates them is glacial erosion.
As for the second question, the process of wearing rocks down into smaller pieces and then taking them away is called weathering. Weathering refers to the various mechanical, chemical, and biological processes that break down rocks and minerals at or near the Earth's surface. It can occur through physical processes like freeze-thaw action, abrasion, and pressure release, as well as chemical processes like dissolution and oxidation.
To answer this question, you would need to have an understanding of the different processes involved in the breakdown of rocks and minerals. By considering the options given, erosion is the correct process as it involves the transportation of weathered rock particles away from their original location. Deposition and condensation are not directly related to the process of breaking down rocks into smaller pieces.
