Answer:
it is the only environment capible of sustaining life.
Explanation:
it has oxygen, water, and its the right temp. those are all needed for life, with them we would not survive.
The pollutants released into the atmosphere cause local air pollution <span>. However, they also cause regional air pollution, as with huge plumes of smoke covering a large area, and acid rain. Beyond that, we are emitting such a high level of pollutants that they are causing serious global environmental problems: climate change and ozone depletion. The human race has become capable of affecting the atmosphere that encircles the Earth, and the very planet itself.</span>
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.
Explanation:
When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. ... However, because light can travel through space, it cannot be a matter wave, like sound or water waves.
When parallel light rays hit a concave mirror they reflect inwards towards a focal point. Each individual ray is still reflecting at the same angle as it hits that small part of the surface. ... Light rays travel towards the mirror in a straight line and are reflected inwards to meet at a point called the focal point. Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy.
Also, when light is reflected from a mirror, it bounces off at the same angle in the opposite direction from which it hit. ... If the surface is concave, or curved inward, a group of light rays from a distant source is reflected back toward a single location known as the focal point
