Why do humans, as one of many on this planet, have the greatest potential to impact all other species?
sdas [7]
Because our brains are the most developed out of all of the other species on this planet. Also, we require the most maintenance to survive. We can’t live in the ocean, such as a fish, shark, dolphin, etc. but we also can’t live in the forest such as bears, deer, coyotes, etc. we need to live in a stable environment when we will have enough food to survive as well to live in certain temperatures that are best suited for our kind. Hopefully that helped a little bit

Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you
den301095 [7]

Answer:

There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).
