Earth is always changing.

What are two forces that cause the earth's surface to constantly change and what are their effects on the planet?

Please answer within a few minutes.

Precipitation, wind, earthquakes, and volcanoes cause the earth's surface to change.

Two forces that cause the Earth's surface to constantly change are tectonic forces and erosional forces.

1. Tectonic forces: These forces are generated by the movement of the Earth's tectonic plates, which are large pieces of the Earth's crust that float on the semi-fluid layer beneath them. The effects of tectonic forces include:

- Plate Boundaries: When tectonic plates interact at their boundaries, different types of forces can occur. For instance, at convergent boundaries, plates collide and result in the formation of mountains or volcanic activity. At divergent boundaries, plates move apart, leading to the creation of new crust and the formation of rift valleys. At transform boundaries, plates slide past each other, resulting in earthquakes.
- Earthquakes: The movement of tectonic plates can create stress and strain in the Earth's crust, leading to the occurrence of earthquakes. These seismic events can cause significant damage to the Earth's surface, buildings, and infrastructure.

2. Erosional forces: These forces are primarily driven by the actions of water, wind, and ice on the Earth's surface. The effects of erosional forces include:

- Weathering: Water and wind erode rocks and minerals over time, breaking them down into smaller pieces through physical or chemical processes. This weathering can alter the Earth's surface and shape the formation of landscapes, such as canyons or cliffs.
- Erosion: The movement of water, wind, or ice can transport eroded materials from one place to another. For example, rivers can carry sediment downstream and deposit it in new locations, reshaping riverbeds and coastlines. Glaciers can carve out valleys and leave behind moraines as they melt.

These forces work continuously, leading to the constant change and evolution of the Earth's surface over long periods of time.

Two forces that cause the Earth's surface to constantly change are tectonic activity and erosion. Tectonic activity refers to the movement of large sections of the Earth's crust, known as tectonic plates. These plates float on the semi-fluid mantle beneath them and interact at their boundaries. The effects of tectonic activity include earthquakes, volcanic eruptions, and the formation of mountains.

To get specific examples, you can search for recent earthquakes, volcanic activity, or the formation of mountains. For earthquakes, you can check the website of the U.S. Geological Survey (USGS) or similar organizations in your country. They provide up-to-date information on seismic activity, including recent earthquakes' magnitudes, locations, and impacts. For volcanic activity, you can look for websites from reputable organizations like the Smithsonian's Global Volcanism Program or volcano observatories in specific regions. These sources provide information on recent eruptions and volcanic monitoring. Lastly, to find information on the formation of mountains, you can search geology textbooks, scientific articles, or online resources that discuss specific mountain ranges or the processes involved in their formation.

Erosion is another force that causes significant changes to the Earth's surface. It refers to the wearing away and removal of rocks, soil, and other materials by natural processes such as wind, water (including rivers, oceans, and glaciers), and ice. Erosion contributes to the formation of various landforms, including valleys, canyons, and coastlines.

To find more information on erosion and its effects, you can search for relevant scientific articles, textbooks, or online resources. Websites of geological surveys or organizations that focus on Earth sciences, such as the United States Geological Survey (USGS) or the Geological Society, provide educational materials and research on erosion.

Remember, these forces are continuously shaping our planet, so there is frequently new research and information available.

Tectonic plate motion is another important factor. It is largely responsible for earthquakes (the Ring of Fire), continental drift, and the existence of mountain ranges.
