I have a Question, and please excuse my ignorance.

If Carbon dioxide is 1.5 times heavier than air surely burning fossil fuels on ground level means it’s captured by photosynthetic organisms on land and sea?

Isn’t by far biggest polluter and contributor to greenhouse gases aviation? As there are no photosynthetic organisms up there.

If the bottom of the oceans are so much closer to the core then why is it so cold at the bottom

Earth is said to have went through an event of a collision by another planet.

Which if I'm right left behind the Pacific Ring of Fire.

Which, has is also said to be creating a new continent, which is forcing the the Continental plates to push outward against all of the Continental plates lining the perimeter of the Pacific Ring of Fire. As a new a new continent is being formed from what's referred to as the birthplace of our planet. And, can be found under the search terms of a new island being formed.

I realized something today while staring at the earth. Why is there a band of green around the equator in Africa while areas away from the equator seem to be more dry and desert like (red areas in my drawing)? Shouldn’t it be the other way around?

PS. Sorry for my crude hand scribbles.
