Answer: A. Air bubbles trapped in a layer indicate how much CO2 was in the atmosphere the year the layer formed.
Explanation:
When ice cores were formed, they included air bubbles that got stuck during the formation. Scientists can study these air bubbles to find out how much carbon dioxide is in them as this will show the proportion of carbon dioxide in air at the time the core was formed.
They can then compare those figures to current carbon dioxide levels to see if there has been a change. This change will give proof of climate change.
Answer: See explanation
Explanation:
Natural resources are the resources that occurs freely which include oil, minerals, water, land, animals, plants, coal etc. As human beings, we need natural resources for our daily survival, hence, it is vital that we conserve them to keep them for future generations and prevent destruction.
Some of the was to conserve natural resources include:
1. Using less water: Water should only be used when it's needed. This will help in preventing its wastage.
2. Using renewable energy such as solar energy or wind energy.
3. Recycling: This simply means reusing of the materials. This will help in avoiding wastage and prevent pollution.
4. Plant a tree
5. Educating people about the importance of conservation.
I would agree. Stress usually impacts general life negatively, it's been scientifically proven. I've never witnessed something that is under stress and is benefiting because of pure stress, it makes not logical sense.
I'm pretty sure the first one is not a crater lol. The last one is a crater, the second one I think is a rift valley, and the first one volcano. Not sure tho as the image is not that clear but the last one is a crater.
I would like to think it's the Middle East and North Africa, which is a part of Africa, Asia, and to some extent, Europe.
