Answer Details
The part of the earth's crust that is covered by oceans and seas is called the hydrosphere.
Let's break it down logically:
The hydrosphere specifically refers to all of the water found on, under, and over the surface of the Earth, including oceans, seas, rivers, lakes, and even water in the atmosphere.
It covers about 71% of the Earth's surface, making it a significant and distinctive part of the planet.
The stratosphere and the ionosphere are layers of the Earth's atmosphere, not related to water or Earth's crust coverage.
The biosphere refers to all regions of the Earth occupied by living organisms. While it includes oceans and seas, it is not specific to just water coverage.
Therefore, the term that correctly describes the part of the Earth's crust covered by water bodies like oceans and seas is the hydrosphere.
