What is the Hydrosphere? – Introduction
Have you ever wondered about the water around us and how it supports life on Earth? The hydrosphere is the part of Earth that contains all the water. It includes oceans, rivers, lakes, glaciers and even the moisture in the air. Let's explore the hydrosphere and learn how it works!
Hydrosphere Key Concepts
Many key concepts are important to understand when learning about the hydrosphere. Let’s learn more about each key concept below!
Water Cycle
The Water Cycle is the continuous movement of water on, above and below the surface of the Earth. Hydrologists, the scientists who study the water cycle, look at how water evaporates from the surface, forms clouds and falls back as rain or snow. The water cycle helps us understand how water is recycled and distributed around the planet.
Bodies of Water
Bodies of water are large accumulations of water, such as oceans, rivers, lakes and glaciers. Each type of body of water has its own characteristics and importance. For example, oceans are vast and salty, whilst lakes are smaller and can be fresh or salty.
Watersheds
A watershed is an area of land that drains all of the streams and rainfall to a common outlet like a river or lake. Watersheds are important for collecting and distributing water across different regions.
Groundwater
Groundwater is the water found underground in the cracks and spaces in soil, sand and rocks. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers. Groundwater is a crucial source of water for drinking, agriculture and industry.
Water Pollution
Water pollution occurs when harmful substances, such as chemicals, waste, or microorganisms, contaminate water. This can affect rivers, lakes, oceans and groundwater, making the water unsafe for drinking, swimming, or supporting wildlife.

The Hydrosphere and Its Components
The hydrosphere includes all terrestrial and aquatic water bodies. It's where all water on Earth exists and interacts with other parts of the environment.
| Term | Definition |
|---|---|
| Bodies of Water | Large accumulations of water, such as oceans, rivers, lakes and glaciers. |
| Water Cycle | The continuous movement of water on, above and below the surface of the Earth. |
| Watershed | An area of land that drains all of the streams and rainfall to a common outlet like a river or lake. |
| Groundwater | Water found underground in soil, sand and rocks, stored in aquifers. |
| Water Pollution | Contamination of water by harmful substances like chemicals, waste, or microorganisms. |
Types of Water Bodies
Water bodies in the hydrosphere fall into two distinct categories: surface water and groundwater. Let’s explore different types of water bodies within both categories.
Surface Water
Surface water is found on the surface of the Earth. Here are some examples:
Oceans: Oceans cover most of the Earth's surface and are home to a vast variety of life, from tiny plankton to huge whales. They play a crucial role in regulating the Earth's climate and weather patterns.
Rivers: Rivers are flowing bodies of freshwater that move from higher to lower elevations. They provide habitat for fish, amphibians and a variety of plants and animals along their banks.
Lakes: Lakes are large bodies of standing freshwater. They support a diverse range of life, including fish, birds and aquatic plants.
Glaciers: Glaciers are large masses of ice that move slowly over land. They store about 68% of the world's freshwater and play a key role in the global water cycle.
Groundwater
Groundwater is water found underground in soil, sand and rocks. It is stored in aquifers and is an important source of water for drinking, agriculture and industry.
Climate Change and the Hydrosphere
Climate change affects the hydrosphere by altering water temperatures, sea levels and precipitation patterns. Conservation and sustainability are crucial to protecting our hydrosphere and ensuring that all water sources remain clean and available for future generations.
Conservation involves protecting water resources and reducing pollution. Sustainability means using water wisely so it lasts for future generations. These are both vital to ensure that the hydrosphere thrives for future generations.
