The sedimentary rock in question is sandstone.
Sandstone is a clastic sedimentary rock made up mostly of weathering sand size debris that accumulates where the waters are slower.
Sandstone is formed by all of the processes named above.
-weathering of the rocks
-erosion caused by water and wind
-transportation by water bodies
-deposition by the water masses where they are slower
-lithification under the pressure
-compactation while mixing with multiple other sediments.

Explanation:
The continental drift is the theory that continents of the earth have moved relative to the other continents over the period of time. Therefore, the continents appear and are said to be drifted or moved across the ocean bed. This theory was fully developed by Alfred Wegener in 1912. This hypothesis was supported by the following evidences
1. the fossils of the plants and animals are found on the shores of continents that were once joined.
2. The continental coastlines fit together in a puzzle-like manner.
3. The similarity in the rock groups present on the continents that were once joined.
Answer:
Explanation:
<u>Renewable resources</u>
Renewable resources are the ones that can be replenished again and again i.e. they can't get exhausted after the use. On to other hand, non renewable energy resources can't be replenished again and again and can become exhausted after the usage .
For example ,
A) fossil fuel:
<u>
Economically </u>fossil fuels are very cheap and hence widely used in economically poor areas.
Fossil fuels has the adverse effects on environment as their burning releases carbon dioxide in the atmosphere, which is the main reason for global warming.
<u>
Benefits:</u> It is very cheap and hence anyone can afford it. Economies of poor countries are very much dependent on the
They are easily accessible and do not need much of technological advancement or heavy machinery.
<u>2. Solar energy:</u>
<u>
Economical cost</u>: Economically it is very expensive and hence it's usage is limited to rich countries only. Silicon used in it is very expensive.
<u>
Environmental: </u>It is environment friendly and so it is a clean source of energy.
<u>
Benefits:
</u>
In this world of drastically changing global climate, increasing pollution and with highly burdened energy resources, solar energy is turns out to be a Savior. It is pollution free and has unlimited abundance .
