I was a bit lost in the wording but I think I understand now...
When the lunar eclipse is in action, the earth's umbra thing will start covering the moon, making it possible to see it. When the earth's umbra completely covers the moon it will either have a red, brown or even sometimes a yellow look to it.
I think this was correct but I'm not sure about that. If this was wrong I'm really sorry and hope someone can give you the right answer for this.
Glaciers carry soil from one place to another. This means that a lot of the fertile soil used mainly for that one area could have been taken away and effected negatively because the fertile soil on the bottom isn't as good as the one on the top, which has been dragged away by glaciers. However, it can take soil to environments where soil is needed, helping it.
(So sorry but the same questions get the same answers lol)
Answer:
Option (C)
Explanation:
CO₂ is one of the main green house gases on earth. A small increase in its concentration can lead to significant changes on earth. When the incoming solar radiations are incident on the earth's surface, some of the energy is absorbed by the atmosphere and the earth's surface. And some of the energy from the land surface after absorption is released into the atmosphere in the form of infrared radiations. The escaping of these radiations from earth is directly dependent on the concentration of CO₂. An increase in the amount of CO₂ will not allow these IR radiations to be removed, and this will result in the global rising of the temperature, leading to catastrophic changes.
Thus, the correct answer is option (C).
Answer:
Rocks found on different mountains are different ages.
Explanation:
Radiometric dating of rocks and fossil records gives scientists an idea of the timelines of certain organisms. Fossils of long dead species found in different strata of rocks can be used to speculate the age and changes these organisms have experienced overtime.
Fossils found in the uppermost strata are indicative of organisms that died not quite long whereas fossils found in lower layers are indicate of organisms that died a long while ago. These studies also provide insight into the changes that the earth has experienced overtime.
