The Polarstern will enter an ice floe and and establish research outposts on surrounding ice sheets to study climate change at the North Pole.
Answer:
The dark energy is one of the primary composition of the universe, which is not visible and are mysterious. as a very little is known about this energy. This dark energy makes up nearly 68% of the universe. It is often considered as a property of space. The presence of dark energy can be detected as it affects the expansion of the universe. The universe started to form right after the big bang explosion and since then the space is expanding in all direction. With this, the dark energy present in the universe also is expanding at a considerably faster rate in association with the Cosmic Microwave Background (CMB) radiation. The measurements of the distance and their connection with the redshift provided an evidence that the universe has been expanding at a certain speed.
Answer:
Option (5)
Explanation:
The ultraviolet rays are found to be present in solar radiation and are allowed to be incident on the earth. These solar radiations are comprised of nearly 8% of UV rays. These UV rays are of three types, namely UV-A, UV-B and UV-C which are harmful to the living organisms on earth. Of all the three, the UV-B and UV-C are highly dangerous that can cause various skin diseases like cancer.
The presence of the ozone layer in the atmosphere acts like a blanket that does not allow these harmful UV radiations to enter into the atmosphere of the earth. The majority of the UV-A is able to reach the earth's surface, but they are not able to cause much harm. So, out of this 8% of total UV radiations, a little amount of it is successful in reaching the surface of the earth.
Thus, the correct answer is option (5).
The mineral that can be found in all samples of rhyolite and andesite would be biotite.
The answers that apply are:
1), 2) , 3), 4)
Let's look into them one by one:
1)It is absorbed by Earth.
- Earth is indeed a material that will absorb solar radiation, this is one of the reason why we have a different temperature in the morning and at night.
2)It is reflected by clouds.
- Cloud can reflect solar radiation as it is made up of water particles which can reflect the solar radiation back. This is why in a foggy day the sunlight is dimmer.
3)It is reflected by glacial ice.
-Glacial ice can reflect solar radiation. As glacial ice is smooth and light in colour,much solar radiation that was on the glacier is reflected, this is one of the reason how the North Pole and South Pole are cold all year.
4)It is condensed into visible light.
Solar radiation can light up the area depending on it's intensity, the more intense the radiation is,the brighter it will be.
5) is amplified by water molecules.
Although water molecules can keep the radiation as it has a high specific latent heat, it does not amplify the solar radiation.
Hope it helps!
