The hydrosphere encompasses all water found on, under, and over the surface of the earth, including oceans, lakes, and rivers.

The continental shelf is the shallow, submerged extension of the continent that extends from the shoreline to the shelf break.

With 33.7% salinity, the Dead Sea is one of the world's saltiest bodies of water. The Dead Sea is landlocked and in the lowest valley on earth. All the minerals of the surrounding countryside get washed into one pool, which in turn gets baked by the sun. This concentrates the salts so much that the Dead Sea is 10 times as salty as the ocean.

Rivers are the primary source of freshwater for human use and ecosystems, as they collect runoff from precipitation.

Deep sea sediments are largely composed of the remains of microscopic organisms (like foraminifera and diatoms) that settle on the ocean floor.

Approximately 71% of the Earth's surface is covered by water, which constitutes the hydrosphere.

The most abundant dissolved ions in seawater are sodium, chloride, magnesium, sulfate and calcium. Its osmolarity is about 1000 mOsm/l.

The Himalayan mountain region is located along a major tectonic plate boundary (the collision zone between the Indian and Eurasian plates), making it one of the most seismically active and earthquake-prone areas in the world.

Expansion of agriculture often involves deforestation and land clearing, which contributes to air pollution rather than containing it.

While carbon dioxide is a greenhouse gas, it is often classified as a pollutant in the context of global warming and air quality management when emitted in excess.
