10 points about significance of continent
Answers
Answer:
A continent is one of several very large landmasses. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents geopolitically. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.[1] Variations with fewer continents may merge some of these, for example some systems include Eurasia or America as single continents.
Geologically, the continents correspond to areas of continental crust that are found on the continental plates, but include continental fragments such as Madagascar that are not counted among the geopolitical continents. Some geological continents are largely covered with water, such as Zealandia (see submerged continents below). Continental crust is only known to exist on Earth.[2]
Oceanic islands are frequently grouped with a neighbouring continent to divide all the world's land into geopolitical regions. Under this scheme, most of the island countries and territories in the Pacific Ocean are grouped together with the continent of Australia to form a geopolitical region called Oceania.
Explanation:
The significance of continents.
Explanation:
- A continent is known as a larger landmass and is made of the active plate tectonics and there exist seven major continents in the world.
- They are the African, the North American, the South American, the Australian, the European, and the antarctica and the Asian continent.
- Most of the continents are located in the northern hemisphere making it the land sphere and oceans in the southern hemisphere as water sphere.
- Higher amounts of temperature and salinity are found near the continents due to the factors of continentality.
- By surface area asia 44,579,000 km sq, is the largest, followed by africa 30,370,000 km, then north america 24,709,000 km sq, and then south america 17,840,000 km which is followed by the antarctic 14,000,000 km sq. europe 10,180,000 km sq. and australia 8,600,000 km sq.
- Asia has the largest population of 60%, Africa has 17%, North America has 7.7%, South America is 5.6%, Antarctica 0%, Europe with 9.7%, and Australia with 0.5%.
- The continental crust is made of the metamorphic and igneous rocks and largely of the granite composition.
- Continents have a diversity of flora and fauna and hence are biological hotspots of the planet.
- Continental crust is only known to exist on earth.
- Continents thickness and depth varies from place to place and all were once connected by the land bridge.
