Explanation:
- Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
- Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
- Mechanical weathering involves:
Abrasion, freezing, thawing, exfoliation.
- Whereas Chemical weathering involves:
dissolution, oxidation, carbonation, hydrolysis.
The most appropriate answer would be magma. Lava is a magma that reaches the Earth's surface, which is technically it is also a magma, and magma is located below the Earth's surface.
Lava at Earth's surface or magma below Earth's surface cools and harden to form mineral crystals.
Answer:
Weightlessness.
A breakdown in the Universe as objects would move out of their orbits.
Muscle athropy and osteoporosis
Explanation:
All objects would move freely in space and also on earth. Due to this loss of mass, the human body's bones and muscles will have no weight on them hence leading to them shrinking. On a larger scale there will be no orbits to hold planets and other celestial bodies in place.
The percentage of languages that are dying out in Asia is only around 20% from the total number of languages dying out in the world, despite it having around 60% of the global population is due to two reasons:
- <em>Number of languages;</em>
Asia, even though it has around 60% of the world's population, it only has around one third of the languages spoken in the world, so automatically there's a big disproportion between the number of population and number of languages, thus giving it a smaller percentage of languages dying out.
- <em>Keeping the tradition;</em>
Lots of Asian nations are not very willing to let their traditional language to die out and continue to speak it. Apart from the traditional point of view, another reason is that Asia has global economic powers, so learning languages like the English or Spanish are not of great benefit in general, so the pressure is much lesser.
