Answer:
Factors responsible for changes on Earth's surface:
There are several factors responsible for bringing changes on the surface of the Earth. Some of the major factors are discussed below:
1. Tectonic forces:
Tectonic forces include processes like plate tectonics, earthquakes, volcanic eruptions, and mountain building. These forces are responsible for the creation of new landforms and the destruction of existing ones. Plate tectonics is the key process that drives the movement of the Earth's crust.
2. Gravitational force:
The gravitational force of the Earth is responsible for many changes on its surface. It causes erosion, weathering, and mass wasting. Erosion is the process by which the surface of the Earth is worn away by the action of water, wind, or ice. Weathering is the breakdown of rocks into smaller pieces due to the action of weather. Mass wasting is the downhill movement of soil and rock under the influence of gravity.
3. Electromagnetic radiation:
Electromagnetic radiation from the sun is responsible for many changes on the Earth's surface. It causes weather patterns, ocean currents, and the growth of plants. The sun's energy is also responsible for the water cycle, which is the process by which water evaporates from the surface of the Earth and is later returned as precipitation.
Correct answer:
All of the above (1, 2, and 3) are responsible for bringing changes on the surface of the Earth.
Which of the following is responsible for bringing changes on the sur...
- Gravity causes movement of ocean current, induces landslides, influences river movements etc. causing dynamic change on the landscape of Earth.
- Tectonic forces can build mountains.
- Sun’s radiation, that is, light, is electromagnetic. All landforms and life on Earth ultimately come from the Sun.
