Study Notes
Domains of the Earth
- Earth has four major zones: land, air, water, and the zone of living things
- These zones are also called spheres
- The lithosphere is the solid part of the Earth
- Includes features like mountains, valleys, and hills
- Continents are large landmasses separated by oceans
- The continents are Asia, Africa, North America, South America, Europe, Australia, and Antarctica
- India is located in Asia
- Soil is the uppermost layer of the Earth's crust
- Composed of rocks, minerals, water, air, and organic matter
- Supports life on Earth indirectly, as living beings depend on plants for food
- Almost 97% of water is salty, while 2% is frozen in glaciers and polar ice caps. Only 1% is suitable for drinking
- Glaciers are large masses of ice formed by snow on mountains, moving slowly
- The atmosphere is a layer of air surrounding Earth, a mixture of gases, water vapor, and dust particles
- Acts as a protective blanket absorbing harmful sun rays, preventing them from entering the Earth, and keeping the Earth warm.
Importance of Water
- Water is a precious, renewable resource
- Essential for all living things to drink and plants to make food
- Used for irrigation, manufacturing goods, domestic purposes, and transportation
- Also a source of important minerals (oil, petroleum, natural gas)
- Provides food (fish, crabs, prawns, water chestnuts, lotus stems)
- Water is used for trade and travel
Importance of Atmosphere
- The atmosphere is vital for all living beings
- Acts as a medium for heat and sound transmission
- Important for transportation
- Influences Earth's climate
- Its ozone layer protects Earth from harmful solar radiation
Biosphere
- Biosphere is made of two parts: 'life' and 'sphere'
- Refers to the part of Earth with life
- Contains all living things: plants, humans, animals, etc.
- Includes parts of all the Earth's spheres (atmosphere, hydrosphere, lithosphere) where life exists
Structure of the Atmosphere
- The atmosphere is divided into five layers
- The layers differ in thickness and temperature
- The troposphere is the lowest layer, where weather changes occur
- The stratosphere contains the ozone layer, which absorbs the Sun's harmful UV rays
- The mesosphere is above the stratosphere
- The thermosphere is above the mesosphere
- The exosphere is the outermost layer, protecting from some radiation from the sun
- The atmosphere is a mixture of various gases, water vapors and dust particles
- It acts as a blanket, absorbing harmful sun rays and preventing them from entering the Earth
- It keeps the Earth warm
- Includes water vapor and dust particles
- The layers, from lowest to highest are: Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.
- Observation rockets and unmanned satellites are in the exosphere
