Continents
Continents are large landmasses on the Earth’s surface. They are separated by oceans and cover about 29% of the Earth’s total area. Continents are composed of various geological formations, including mountains, plains, and deserts. They also have distinct climates, ecosystems, and cultures.
Geological and Geographical Significance of Continents, Continents and oceans worksheet answer key
Continents play a crucial role in the Earth’s geological and geographical processes. They are formed by the movement of tectonic plates and are shaped by erosion, weathering, and other geological forces. Continents are home to a wide variety of mineral resources, including metals, gemstones, and fossil fuels.
They also have a significant impact on the global climate and ocean currents.
| Continent | Area (km²) | Population (2023) |
|---|---|---|
| Asia | 44,614,000 | 4.7 billion |
| Africa | 30,365,000 | 1.4 billion |
| North America | 24,709,000 | 366 million |
| South America | 17,840,000 | 438 million |
| Antarctica | 14,200,000 | No permanent population |
| Europe | 10,180,000 | 748 million |
| Australia | 8,525,989 | 26 million |
Oceans: Continents And Oceans Worksheet Answer Key
Oceans are vast bodies of saltwater that cover about 71% of the Earth’s surface. They play a vital role in regulating the Earth’s climate and providing habitat for a diverse range of marine life. Oceans are classified into five major basins: the Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean, and Southern Ocean.
Physical and Chemical Characteristics of Oceans
Oceans have distinct physical and chemical characteristics that vary depending on their location and depth. These characteristics include temperature, salinity, density, and nutrient content. Oceans also have complex currents and tides that influence marine ecosystems and global weather patterns.
| Ocean | Depth (m) | Salinity (‰) | Temperature (°C) |
|---|---|---|---|
| Pacific Ocean | 3,940 | 34.7 | 19.4 |
| Atlantic Ocean | 3,339 | 35.4 | 16.9 |
| Indian Ocean | 3,963 | 34.8 | 17.3 |
| Arctic Ocean | 1,205 | 32.0 | -1.8 |
| Southern Ocean | 3,270 | 34.2 | 2.0 |
