Limestone. limestone is the youngest.
Answer:
A. elevation
Explanation:
The elevation is the factor that influences the variety of temperatures within both the Rocky Mountains and the Himalayan Mountains because, with elevation, the temperature reduces on the mountain. at the bottom of the mount the temperature is milder while at the head of the mountain, the temperature is cooler and very low. So we can say that altitude is the principal factor in the variety of temperatures in mountains.
Answer:
Leaves are the most important
Explanation:
Leaves are directly exposed to sunlight and contains chlorophyll which is the chemical that makes them green and is key in photosynthesis.
The Mars atmosphere is 100 times thinner than earth's atmosphere. Mars atmosphere has 95% of carbon dioxide, that is why people like astronauts can't go there without their suit because there is no oxygen on Mars or in space.
But Mars was confirmed to have water inside of it's rocks and when there is water it will recycle the air and produce oxygen. That's how Earth has oxygen because we have water and trees.
So I will say in approximately 100 years or so from now, Mars will be able to produce life, water, trees, organisms, etc. But right now the water is just the start of it.
Hope this helped :)
Have a great day <span />
