Earthquakes and valcanoes change Earths surface quickly. Can you name at least two processes that canchange earhts surface slowly?
wind erosion
water erosion
human disturbance
tell weather my type of erosion gradual change or instaneous changemy type is gravity
Certainly! Two processes that can change Earth's surface slowly are weathering and erosion.
1. Weathering: Weathering is the process by which rocks and minerals are broken down into smaller pieces. It occurs through physical, chemical, and biological processes. Physical weathering includes the mechanical breakdown of rocks by temperature changes, freezing and thawing, wind, and water. Chemical weathering involves the alteration of rocks through chemical reactions, such as exposure to water, oxygen, and acidic substances. Biological weathering occurs when living organisms, like tree roots or burrowing animals, contribute to rock breakdown.
To witness the process of weathering, you can observe rocks over an extended period of time. Take note of any changes in their size, shape, or overall appearance. You may also notice the accumulation of small fragments around the rocks, which are the result of weathering.
2. Erosion: Erosion is the process of transporting and removing weathered materials, such as rock fragments and soil, from one place to another. It is primarily driven by the action of wind, water, or ice. Over time, erosion can shape the landscape and create features like valleys, canyons, and deltas.
To understand erosion, you can study different landscapes and observe the effects of moving water, wind, or glaciers. You might notice riverbanks slowly eroding away or sediment deposition at the mouth of a river. By observing these changes and their impact on the landforms over time, you can appreciate the gradual but significant effect erosion has on Earth's surface.
Remember, while earthquakes and volcanoes can cause rapid changes to Earth's surface, the processes of weathering and erosion occur slowly but continuously, shaping our planet over millions of years.
