What is the process for when tectonic plates are pulled apart? (1 point)
A. erosion
B. extension
C. lithosphere
D. possibilism
E. ecology
B. extension
The correct answer is B. extension.
When tectonic plates are pulled apart, the process is referred to as extension. This occurs at divergent plate boundaries where two plates move away from each other. As the plates move apart, magma from the mantle rises to fill the gap between them, creating new oceanic crust. This process is responsible for the formation of mid-ocean ridges and the creation of new ocean basins. It is also associated with volcanic activity and earthquakes.
The correct answer is B. extension.
When tectonic plates are pulled apart, the process is known as extension. This typically occurs at divergent plate boundaries, where two plates move away from each other. The extension is caused by the forces exerted by the underlying mantle, which may create tensional stresses along the boundary.
To arrive at this answer, you can follow these steps:
1. Understand the question: The question is asking about the process for when tectonic plates are pulled apart. You need to identify the specific process involved in this scenario.
2. Analyze the options: Look at the options provided - erosion, extension, lithosphere, possibilism, and ecology. Focus on the option that describes the process of tectonic plates pulling apart.
3. Eliminate irrelevant options: Erosion, lithosphere, possibilism, and ecology are not directly related to the process of tectonic plates being pulled apart. These options can be eliminated.
4. Determine the correct answer: The correct answer is extension. This term refers to the stretching and pulling apart of tectonic plates at divergent plate boundaries.
By following this process of elimination and understanding the context of the question, you can correctly identify the answer as B. extension.
