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

4. protects us from the harmful rays emitted by the sun.
5. is a predominantly silt-sized sediment formed by the accumulation of windblown dust.
7. are flat and broad land areas that have no great changes in elevation when measured with reference to the mean sea level.
9. are elevated portions of lands that are formed by geologic activities such as faulting.
10. is the scientific study of landforms and the processes that shape them.
12. is the study of the flow of matter primarily in the liquid state under conditions at which they respond with plastic flow rather than deforming elastically in response to an applied force.
15. is the study of the current terrain features of a region and the graphic representation of a particular landform on a map.
16. is the outermost layer of Earth.
18. are defined as the natural physical features on the surface of Earth.
19. is the study of scientists who inferred that our planet is made up of different layers.

1. is used to detect the magnetic field.
2. is typically a low-lying triangular area located at the mouth of rivers where it meets an ocean, seas, or estuaries.
3. is also called byland or biland, is a piece of land that projects into a body of water and is connected to the mainland by an isthmus.
6. is the outer solid part of the planet include Earth's crust as well as the underlying cool, dense and rigid upper part of the upper mantle.
8. is also known as table lands or flat-topped mountains, are portion of lands elevated thousands of feet above their surroundings.
11. is the last and the innermost layer which is separated into the liquid outer core and the solid inner core.
13. represents about 4% of the mantle-crust mass.
14. is a bend in a sinuous watercourse of river.
17. can be found at the deepest region of the planet.
20. is sometimes called gorge, a deep ravine between cliffs that is often carved from the landscape by a river, wind, or glacier.
