Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.
Answer:
Explanation:
Spatial competition occurs when the amount of space available is inadequate to satisfy existing or expected future wants. For example space for transport or agriculture may be at the expense of space for ecosystems
Answer:
The correct answer is B: The greater the angle of the fault, the greater the compression of the crust.
The most basic features to form in sedimentary basins under extension are normal faults. <em>Normal faults are generally fairly steep</em>, ie <em>have a high dip angle.</em> A fault will form in the crust when the extensional forces acting on it are great enough to cause failure along a fracture plane.

Glaciers can move erosion products over long distances.

Answer:
Overlay is a GIS operation that superimposes multiple data sets (representing different themes) together for the purpose of identifying relationships between them.[2]. An overlay creates a composite map by combining the geometry and attributes of the input data sets. Tools are available in most GIS software for overlaying both Vector or raster data.
Explanation:
Before the use of computers, a similar effect was develioped by Ian McHarg and others by drawing maps of the same area at the same scale on clear plastic and actually laying them on top of each other.
