Continental drift is a scientific theory was developed by Alfred Wegener (1880-1930). He was a German meteorologist, who proposed the hypothesis that continents were the part of huge landmass or supercontinent about 200 million years ago. These continents got separated or splitted from their parent  continent and drifted to other locations. He named the parent or supercontinent as "Pangaea" (which means "all lands" in Greek) which began to break up.

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.
