Study Notes
Four Domains of Earth
- Life is supported on Earth due to four main domains: Lithosphere, Hydrosphere, Atmosphere, and Biosphere.
- The interaction of land, water, and air creates the biosphere, the domain of living organisms.
Lithosphere
- Lithosphere refers to the land on Earth's surface, covering approximately one-fourth of it.
- Composed of soil and rocks, it provides habitat for humans, animals, and plants.
- The Northern Hemisphere contains the majority of the Earth's land, earning it the title of the "land hemisphere."
- Seven continents exist: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
Features of the Continents
- Asia: Largest continent; home to Mount Everest (highest peak) and the Dead Sea (lowest point).
- Africa: Second-largest; features the Sahara (largest desert) and Nile (longest river).
- North America: Connects to South America via the Isthmus of Panama; Rocky Mountains and Mississippi River are notable.
- South America: Contains the Andes Mountains and the Amazon River (largest river).
- Antarctica: Known as the "white continent" due to ice coverage; includes Transantarctic Mountains and Lake Vostok.
- Europe: Together with Asia, forms Eurasia; features the Alps and Danube River.
- Australia: Smallest continent; notable for the Great Dividing Range and Murray River.
Hydrosphere
- Hydrosphere encompasses all water on Earth, covering about three-fourths of the surface.
- Most water is located in the Southern Hemisphere, termed the "water hemisphere."
- Earth's water volume has remained constant since its formation, linking ancient water to present sources.
- Five major oceans: Pacific, Atlantic, Indian, Antarctic, and Arctic.
Details of Earth's Oceans
- Pacific Ocean: Largest and deepest; houses Challenger Deep (deepest point) and the Great Barrier Reef.
- Atlantic Ocean: Second-largest; features the Mid-Atlantic Ridge (underwater mountain range) and Greenland (largest island).
- Indian Ocean: Exclusively named after a country; warmer water temperatures than other oceans.
- Antarctic Ocean: Surrounds Antarctica; smallest and shallowest ocean, remaining frozen in winter.
- Arctic Ocean: Covered with sea ice year-round; valuable for understanding climate impacts.
Atmosphere
- Atmosphere is the layer of air surrounding Earth, sustained by gravity.
- Composed of gases (mainly nitrogen and oxygen), water vapor, dust, and smoke.
- Essential for life: provides oxygen for respiration, carbon dioxide for photosynthesis, and protection from harmful solar radiation.
- Regulates Earth's temperature, preventing extremes.
Biosphere
- Biosphere is the domain of living organisms, where lithosphere, hydrosphere, and atmosphere converge.
- Comprises all life forms, including plants, animals, humans, and microbes, interacting within their environments.
