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.
The oceanic lithosphere consists of the upper part of the Earth's crust that is submerged beneath the oceans. It is primarily made up of basalt, but can consist of other forms of sediment deposited by rivers or currents; the basalt feature exists due to the oceanic lithosphere's creation via divergent tectonic activity. The continental shelf is a portion of the crust that is of higher elevation than the rest of the ocean due to its connection to the less dense continental lithosphere. The continental slope, therefore, is the portion of the crust where the continental shelf decreases in elevation as it meets the denser oceanic lithosphere. Abyssal plains are portions of the lithosphere far from spreading centers - they consist of rocks older than those near rifting centers. Due to the coolness of the plate and their distance from rifting centers, abyssal plains are some of the lowest continuous portions of the lithosphere (cool rock is denser and thus sinks to a lower elevation). Since they are very much inactive, abyssal plains are coated with sediment and are very, very flat.
Answer:
Tectonic plates are very thick and earthquakes are mostly unavoidable
They represent areas of equal pressure<em /><em /> because they are isobars.

The position of a place north or south of the equator is described
in terms of its latitude. Since we're talking about the surface of
a sphere, latitude is an angle, and its value is given in angle
measure.
Any unit of angle is fine ... degrees, radians, grads, etc., and if
you're given an angle in one unit, you can always easily change
it to a unit that you like better ... but 'degrees' has been the unit
used most often for latitude, and longitude too, practically since
the whole system was invented a few hundred years ago.
For parts of an angle smaller than a whole degree, 1/60 of a
degree (minutes) and 1/3600 of a degree (seconds) were used
traditionally for the first couple hundred years. But that ponderous,
inconvenient system is rapidly giving way now to plain old decimal
degrees, probably because those are easier for the computer to handle.
