Study Notes
Earth's Hydrosphere
- 97% of Earth's hydrosphere is saltwater.
- 68.9% of Earth's fresh water is located in ice caps, glaciers, and permanent snow.
- The continuous change in the shape of Earth's hydrosphere is caused by the water cycle and the movement of tectonic plates.
- The estimated total mass of Earth's hydrosphere is approximately 1.386 billion cubic kilometers.
Fresh Water Distribution
- The smallest percentage of Earth's fresh water is located in rivers, lakes, and wetlands, which accounts for only 0.3%.
Climate and Weather
- Climate refers to the long-term average atmospheric conditions in a particular region, including temperature, humidity, and precipitation.
- Climate is determined by factors such as latitude, altitude, and the presence of oceans and mountains.
- Weather, on the other hand, refers to the short-term and local conditions of the atmosphere, including temperature, humidity, cloudiness, wind, and precipitation.
- The main element of weather and climate discussed in the chapter is water.
- Climate gives an average of temperature, precipitation, and other atmospheric conditions for a country or region over a long period of time.
