What is the land area of Africa?​

11.73 million mi²

Explanation:

Africa is the world's 2nd-largest and 2nd-most populous continent, after the continent of Asia in both cases. At 30.37 million km² including islands, it covers six percent of the planet Earth's total surface area and 20 percent of its land area. With 1.3 billion people as of 2018, it accounts for about 16 percent of the world's total human population.

The answer is 30.37 million km².

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
