Answers
1.The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. 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. Exogenic factors are usually driven by gravity or atmospheric forces
3.Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
4.Floodplains. 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. Erosion removes any interlocking spurs , creating a wide, flat area on either side of the river.
5.A dune is a landform, and is a large mass of wind-blown sand. Dunes are most common in deserted environments, such as the Sahara, and also near beaches. An area with dunes is called a dune system. In physical geography, a dune is a hill of loose sand built by aeolian processes or the flow of water.
6.Beaches are wave-deposited accumulations of sediment located at the shoreline. They require a base to reside on, usually the bedrock geology, waves to shape them, sediment to form them, and most are also affected by tides.

1. The main driving force of plate tectonics is gravity. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle. However, convection also drives plate tectonics.
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. Exogenic factors are usually driven by gravity or atmospheric forces.
3.The process of eroding or being eroded by wind, water, or other natural agents.
4. The question is wrong I guess.
5. A dune is a landform and is a large mass of wind-blown sand. Dunes are most common in deserted environments, such as the Sahara, and also near beaches. An area with dunes is called a dune system.
6. Beaches are made up from eroded material that has been transported from elsewhere and then deposited by the sea. For this to occur, waves must have limited energy, so beaches often form in sheltered areas like bays .
7. An oxbow lake is a U-shaped lake that forms when a wide meander from the main stem of a river is cut off, creating a free-standing body of water. This landform is so named for its distinctive curved shape, which resembles the bow pin of an Oxbow.
