The lithosphere floats on the asthenosphere like glass on clay. when the clay moves, the glass moves. the movement of the lithosphere is

seafloor spreading
plate tectonics
volcanic activity
earthquakes

Option (2)

Explanation:

The lithosphere is the region that is comprised of the crust and a portion of the upper mantle. It is a region where all the essential minerals are present and also the living beings exist. It is made of rocks of variable composition. The lithosphere is made up of numerous large and small plates that are constantly in motion over the less dense asthenosphere layer, due to the convection current that generates in the mantle. This convection current initiates because of the heat radiated from the core of the earth.

Thus, this movement of the lithosphere is known as the plate tectonic movement.

Hence, the most appropriate answer is option (2).

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
