Sedimentary rocks cover "5%" of the "Earth’s outermost 10 Km" of "rock" while "75%" of "Earth’s continental area" is covered.
Option: C
<u>Explanation</u>:
These rocks covered 5% of the Earth's outermost 10 kilometers of rock (first %) while 75% of the Earth's continental area is covered (second %). These were originated from metamorphic rocks, pre-existing igneous and sedimentary rocks. Some common sedimentary rock types are Sandstone, shale, Limestone, Conglomerate, Chemical and Organic sedimentary rocks. These rocks are resulted from lithification of sediments, precipitate out from solution and consolidation of the remains of plants and animals and its example is Coal.
A laccolith is an intrusion with the shape of a mushroom that grows under the earth's surface. This happens when liquid magma exceeds its way between 2 layers of rock, causing the overlying sediments to puff out as the feature increases. Eventually, this causes the origin of small hills and mountains surrounding the top of the mountain.
