EARTH SCIENCE

4. Refers to transferring of unconsolidated earth’s material via agents like human animal wind and water.
5. This is a force that causes hotter less dense material to force itself up through a ridge
6. It is an aggregate of minerals or minerals which may not contain organic matter.
7. wedging It is a process that involves repeated cycles of freezing and thawing of ice.
8. It is a dynamic planet composed of interacting subsystems, namely: atmosphere, hydrosphere, lithosphere, and the biosphere.
11. When magma rises to the crust it can displace the host or country rock to form structures called?
13. It fuels the planet’s dynamic processes including plate movements, earthquakes, and volcanism.
15. It is the vulnerability of soil to erosion caused by rainfall intensity soil properties crop cover and slope.
16. This is a type of rock formed from preexisting rocks and fossils of organisms
17. It is the rigid outermost layer of earth that is composed of crust and the uppermost layer of the mantle
18. It is a process of changing the characteristics of a rock as a result of changes in temperature, pressure, or reactions with hot fluids

1. plates These are slabs of the brittle lithosphere which can be able to move due to the plasticity of the underlying asthenosphere
2. This is one of the types of mass wasting that have a slow downhill movement.
3. Known as radioactive dating of hotspots show age differences based on plate movements.
5. It is a process where there is growth in the size of mineral grains of pre-existing materials
7. It is a discernible displacement where rocks grind or slide past each other.
9. It occurs along the plate boundaries or margins and sometimes within the plate.
10. These are substances that evaporate easily and can exist in gaseous form on the surface of earth
12. It is the process of breaking down rocks present at earth’s surface.
14. it is a hill or mountain where lava pyroclastic materials and gases erupt
