16: BIOSPHERE
Biosphere :- The outer layer of the planet Earth can be divided into several compartments: the hydrosphere (or sphere of water), the lithosphere (or sphere of soils and rocks), and the atmosphere (or sphere of the air). The biosphere (or sphere of life), sometimes described as "the fourth envelope," is all living matter on the planet or that portion of the planet occupied by life. It reaches we...
17: WORLD CLIMATE ZONES
WORLD CLIMATE ZONES :- Climate is the characteristic condition of the atmosphere near the earth's surface at a certain place on earth. It is the long-term weather of that area (at least 30 years). This includes the region's general pattern of weather conditions, seasons and weather extremes like hurricanes, droughts, or rainy periods. Two of the most important factors determining an area's clim...
18: HYDROSPHERE (INTRODUCTION)
INTRODUCTION :- The abundance of water on Earth's surface is a unique feature that distinguishes the "Blue Planet" from others in the solar system. The Earth's hydrosphere consists chiefly of the oceans, but technically includes all water surfaces in the world, including inland seas, lakes, rivers, and underground waters down to a depth of 2,000 m. The deepest underwater location is Challenger...
19: METEOROLOGY
Meteorology :- Meteorology is the scientific study of the atmosphere and weather. A person who studies the weather is called a meteorologist. Meteorologists use many different tools to learn about the weather in the world. Meteorologists and Weather Forecasters are very important because they can predict what the weather is going to be like in the future. To do this, they use very specialize...
20: PRECIPITATION
PRECIPITATION : The process of continuous condensation in free air helps the condensed particles to grow in size. When the resistance of the air fails to hold them against the force of gravity, they fall on to the earth's surface. So after the condensation of water vapor, the release of moisture is known as precipitation. This may take place in liquid or solid form. The precipitation in the for...
