What are some of the forces that change earth's surface
Hurricanes, tornadoes, wind, rain, earthquakes, tsunamis, volcanoes, and glaciers are natural events that change the earth's surface.
People also change the earth's surface by damming rivers, using water that used to flow into lakes, bulldozing hills, paving roads and parking lots, dynamiting big holes for mining and gravel collection.
One of the most spectacular sights that I've seen is a huge hole hundreds of feet deep and at least a half mile in diameter just southwest of Chicago. It's a gravel mine that an interstate highway crosses on a bridge.
thank you so much
You're very welcome.
Some of the forces that change Earth's surface are:
1. Plate Tectonics: The movement of Earth's tectonic plates is a major force that changes its surface over millions of years. Plates can collide, separate, or slide past each other, resulting in the formation of mountains, earthquakes, and the creation of new land.
2. Erosion: Erosion is the process of wearing away the Earth's surface by the action of wind, water, ice, or gravity. These forces can gradually reshape the land through processes like weathering, transport, and deposition.
3. Weathering: Weathering is the breakdown of rocks into smaller particles by physical, chemical, or biological processes. Physical weathering includes actions such as freeze-thaw cycles or root growth, while chemical weathering involves the alteration of rock chemistry through reactions with water or air.
4. Volcanic Activity: Volcanic eruptions can dramatically change Earth's surface. Lava flows, ash deposits, and pyroclastic materials released during volcanic activity can alter the landscape by creating new landforms like volcanoes, craters, or lava plateaus.
5. Glaciation: The movement and melting of glaciers can significantly modify the Earth's surface. Glaciers erode rock and soil, carve valleys, and deposit sediments, changing the topography and leaving behind features like moraines or fjords.
To learn more about these forces and their impacts, you can study various scientific disciplines, such as geology, geomorphology, plate tectonics, and climatology. Reading textbooks, research papers, consulting reputable websites, or discussing with experts in these fields can provide detailed insight into the forces that shape Earth's surface.
