explain what the hydrosphere consists of.
discuss why the hydrosphere is important.
understand that the water in the hydrosphere moves around in a cycle.
draw a labelled diagram of the water cycle.
describe the stages of the water cycle using correct vocabulary: solid, liquid, vapour(gas), evaporation, condensation, melting, precipitation.
describe what global warming is and its effect on the hydrosphere
discuss the effect of climate change(including rising sea level)
According to studies, approximately 71% of the earth’s is covered with water. Water is found in oceans, lakes, rivers, and streams, and is stored underground as groundwater. Some amount is trapped in ice.
Water also exists in the atmosphere in the form of water vapor. All the water that exists on Earth is known as Hydrosphere. Put differently; the hydrosphere is the water component of the Earth. Hence, we can define the hydrosphere as,
The total amount of water on a planet. It includes water on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, and ice.
Effect of Global warming on HYDROSPHERE.
Effect of Global warming on HYDROSPHERE.
How is the hydrosphere changing? Human contributions to greenhouse gases in the atmosphere are warming the earth's surface - a process which is projected to increase evaporation of surface water and accelerate the hydrologic cycle. In turn, a warmer atmosphere can hold more water vapor.
