Answer:

1. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.

2. Endogenic (or endogenetic) factors are agents supplying energy for actions that are located within the earth. Exogenic (or exogenetic) factors are agents supplying energy for actions that are located at or near the earth's surface.

3. In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location.

4. A floodplain is an area of land which is covered in water when a river bursts its banks. Floodplains form due to both erosion and deposition

5. A sand dune is a mount, hill or ridge of sand that lies behind the part of the beach affected by tides. They are formed over many years when windblown sand is trapped by beach grass or other stationary objects.

6. A beach forms when waves deposit sand and gravel along the shoreline. and pebbles. Over time they are worn smooth from being rolled around by waves. The rocks usually reflect the local geology.

7. An oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water.
