  2. Continent - Wikipedia

    en.wikipedia.org/wiki/Continent

    In geology, a continent is defined as "one of Earth's major landmasses, including both dry land and continental shelves". [3] The geological continents correspond to seven large areas of continental crust that are found on the tectonic plates, but exclude small continental fragments such as Madagascar that are generally referred to as ...

  3. Boundaries between the continents - Wikipedia

    en.wikipedia.org/wiki/Boundaries_between_the...

    The continental boundaries are considered to be within the very narrow land connections joining the continents. The remaining boundaries concern the association of islands and archipelagos with specific continents, notably: the delineation between Africa, Asia, and Europe in the Mediterranean Sea;

  4. List of continents and continental subregions by population

    en.wikipedia.org/wiki/List_of_continents_and...

    This is a list of continental landmasses, continents, and continental subregions by population. For statistical convenience, the population of continental landmasses also include the population of their associated islands .

  5. Earth - Wikipedia

    en.wikipedia.org/wiki/Earth

    The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation , while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater , lakes, rivers and atmospheric ...

  6. Continental crust - Wikipedia

    en.wikipedia.org/wiki/Continental_crust

    The thickness of Earth's crust (km). The continental crust consists of various layers, with a bulk composition that is intermediate (SiO 2 wt% = 60.6). [5] The average density of the continental crust is about, 2.83 g/cm 3 (0.102 lb/cu in), [6] less dense than the ultramafic material that makes up the mantle, which has a density of around 3.3 g/cm 3 (0.12 lb/cu in).

  7. List of political and geographic borders - Wikipedia

    en.wikipedia.org/wiki/List_of_political_and...

    (Notes: Dependencies and islands remote from continental land masses [vague] are not considered and are excluded from this list section; thus only continental land borders are considered. The only countries listed either straddle continents or are on a continent border.)

  8. Asia - Wikipedia

    en.wikipedia.org/wiki/Asia

    Asia (/ ˈ eɪ ʒ ə / ⓘ AY-zhə, UK also / ˈ eɪ ʃ ə / AY-shə) is the largest continent [note 1] [10] [11] in the world by both land area and population. [11] It covers an area of more than 44 million square kilometres, [note 2] about 30% of Earth's total land area and 8% of Earth's total surface area.

  9. Landmass - Wikipedia

    en.wikipedia.org/wiki/Landmass

    A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. [1] [2] The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. [3] [4] In the field of geology, a landmass is a defined section of continental crust extending above sea ...
