- ungelating or rolling
- Rugged
What is relief across a terrain
Is the change in height in a specific terrain and there are 3 levels (low, moderate, and high)
What processes cause portions of the land surface to move up or down relative to adjacent areas (2)
- Uplift
- Subsidence
What is the major cause of uplift and subsidence
Plate tectonics
What can convergence produces (2)
- Mountains, by squeezing the crust
- Volcanic uplift
What is volcanic uplift
A result of, material being added to the surface and hot rocks below the surface that take up space (magma chambers)
What causes uplift at divergent boundaries
Uplift at divergent boundaries is created by when the new magma comes to the surface it is hotter than the surrounding rock creating uplift (oceanic divergent boundaries)
What causes subsidence at divergent boundaries
Stretching the crust which creates oceans
What are the ways to create subsidence
- Divergent boundaries (pulling plates apart till they create oceans)
- Adding a load to the crust
Uplift and subsidence create ____ across a terrain
relief (difference in elevation)
What are the types of landforms (4)
- Tectonic landform
- Volcanic landform
- Erosional landform
- Depositional landform
