Question

What is the driving force for the movement of the lithospheric plates? A unequal distribution of heat in the oceans B unequal distribution of heat within Earth C heat from the sun D heat in the atmosphere

Answer 1

The correct answer is (b) Unequal distribution of heat within Earth.

Lithospheric plates can be defined as regions of Earth's crust and upper mantle that are fractured into plates that move across mantle. Earth is made of three layers outer is crust, middle is mantle and the inner one is core. The different layers has different properties. The movement of plates is caused due to the unequal distribution of the heat within earth. This unequal distribution of heat generates a force which is the driving force for the movement of lithospheric plates.

Answer 2

The driving force for the movement of the lithospheric plates is B. unequal distribution of heat within Earth

Further explanation

Lithospheric plates are Earth's crust regions and upper mantle that are fractured into plates which move across a deeper plasticine mantle. The lithosphere is composed of different plates that shift because of Earth’s internal mechanisms.

Lithospheric plates' movement produces landmasses and their mountains and the oceans basins. There are seven major plates such as North American, South American, Pacific, African, Eurasian, Australian, and Antarctic plates.

The processes responsible for plate movement are very complex. But one mechanism that is relatively easy to visualize involves the unequal distribution of heat within the earth, which drives the movement of plates at an average speed 5 cm per year.

Earth is made of three layers: the outer is crust, middle is mantle and the inner one is core. The different layers has different properties. The movement of plates is caused due to the unequal distribution of the heat within earth. This unequal distribution of heat generates a force which is the driving force for the movement of lithospheric plates.
