Answer:The lithospheric plates move because of the movement of the molten magma inside the earth. The molten magma inside the earth moves in a circular manner.
Answer:The forces which act in the interior of the earth are called as Endogenic forces and the forces that work on the surface of the earth are called Exogenic forces.
Answer:Erosion is the wearing away of the landscape by different agents like water, wind, and ice.
During floods, layers of fine soil and other material called sediments are deposited along its bank. This leads to the formation of a flat fertile floodplain.
Answer:When the wind blows, it takes the sand from one place to another. When it stops blowing, the sand falls and gets deposited in low hill-like structures, these are called sand dunes.
Answer:The beaches are formed when the sea waves deposit sediments along the seashores.
Answer:As the river enters the plain it twists and turns to form large bends known as meanders. Due to continuous erosion and deposition, the ends of the meander loop come closer. In due course of time, the meander loop cuts off from the river and forms a cut-off lake which is called an ox-bow lake.

Answer:In deserts, we can see rocks in the shape of a mushroom, commonly called mushroom rocks. When the wind blows, it lifts and transports sand from one place to another. Winds erode the lower section of the rock more than the upper part. Therefore, such rocks have narrow waves and wider tops.
Answer:When the river overflows through its banks, this leads to the flooding of the neighboring areas. As it floods, it deposits layers of fine soil and other material called sediments along its banks. This lead to the formation of a flat fertile floodplain.
Answer:The erosion and deposition of the sea waves result in coastal landforms. Sea waves continuously strike and the rocks, due to which cracks are developed. Over time they become larger and wider. Thus hollow-like caves are formed on the rocks. they are called sea caves. As these cavities become bigger and when only the roof of the caves remain, it forms sea arches. Then erosion breaks the roof and only walls are left these walls are called stacks.
Answer:When the lithospheric plates move the surface of the earth vibrates. These vibrations are called earthquakes. The vibration can travel all around the earth. An earthquake can cause great destruction. Buildings collapse due to earthquakes. The earthquakes cannot be predicted but we can minimize their impact by preparing beforehand.
