Identify two effects of tectonic plate movement. then explain how tectonic plate movement cause each of the effects you identified.
Please someone help me with this question . The one effect I can think of is they form mountains and volcano but i don't know if it right or wrong.
1. Creation of mountains, volcanoes, earthquakes, and landforms.
2. Evolution of life.
You might want to look it up on Wikipedia.
Go to this site and read. Paragraph #3 is what you are looking for. http://en.wikipedia.org/wiki/Plate_tectonics
You're on the right track! Tectonic plate movements do indeed cause the formation of mountains and volcanoes. Additionally, they also have other effects, such as the creation of earthquakes and the formation of oceanic trenches. Here's an explanation of how tectonic plate movements cause each of these effects:
1. Formation of mountains and volcanoes:
Tectonic plates are large pieces of the Earth's lithosphere that float on the semi-fluid asthenosphere beneath them. These plates are constantly moving, either colliding together, pulling apart, or sliding past each other. When two plates collide, it can result in a compression zone, where one plate is forced under the other. This process is called subduction.
In subduction zones, the top plate is usually composed of continental crust, which is less dense compared to the oceanic crust of the lower plate. As the denser oceanic crust is pushed downwards, it melts and forms magma due to the increase in temperature and pressure. This magma rises through the overlying continental crust, forming a volcanic arc or a line of volcanoes. The accumulation of erupted lava and other volcanic materials over time can lead to the formation of mountains, such as the Andes in South America or the Himalayas in Asia.
2. Creation of earthquakes:
When tectonic plates move past each other, they can get stuck at their boundaries due to friction. As the plates continue to push against each other, stress builds up in the rocks along the plate boundary. Eventually, this stress overcomes the friction, causing the rocks to rupture and release energy. This sudden release of energy, known as an earthquake, causes the ground to shake.
Earthquakes can occur at various types of plate boundaries, such as transform boundaries where plates slide horizontally past each other, or at convergent boundaries where plates collide. These seismic events are often accompanied by strong shaking, ground rupture, and the potential for tsunamis in coastal areas.
It's important to note that plate tectonics is a complex and ongoing process, and the effects mentioned above are just some of the possible outcomes. Different types of plate boundaries and the specific geological conditions in each region can lead to variations in the resulting effects.
