Internal structure of the Earth and the Different Landforms and Processes Involved in their Formation

2. The planet’s source of internal heat.
3. The largest layer of the Earth.
5. The study of the current terrain features of a region and the graphic representation of a particular landform on a map.
10. Portion of lands elevated thousands of feet above their surroundings. They are also known as table lands or flat-topped mountains.
11. The natural physical features on the surface of Earth.
12. Plains that are found at the deepest part of the ocean.
15. Landforms resulted from the actions of glaciers.
18. Landforms created from exclusively erosional and weathering activities.
19. The outermost layer of the Earth.

1. Located below the lithosphere. A highly viscous, hotter, and ductile region of the upper mantle.
2. A deep ravine between cliffs that is often carved from the landscape by a river, wind, or glacier.
4. cliffs High rocky coasts that plunge down to the edge of the sea.
6. The scientific study of landforms and the processes that shape them.
7. Elevated portions of lands that are formed by geologic activities such as faulting. These are smaller than mountains.
8. Mounds or small hills made up of sand.
9. A piece of land that projects into a body of water and is connected to the mainland by an isthmus.
13. Outer solid part of the planet.
14. Study of the flow of matter primarily in a liquid state under conditions at which they respond with plastic flow rather than deforming elastically in response to applied force.
16. Flat and broad land areas that have no great changes in elevation when measured with reference to the mean sea level.
17. A low-lying triangular area located at the mouth of rivers where it meets an ocean, seas, or estuaries.
