What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

Bizarre fact: Physics work as usual.

Of course. That's where the Calm Belt is.

Damn never thought of that

The calm belt might be based on real life horse latitudes where the wind barely blows: https://en.m.wikipedia.org/wiki/Horse_latitudes

Horse latitudes are where the tropics meet the mid-latitudes. The intertropical convergence zone is the one at the equator.

The difference is that the ITZ is often rainy because of the rising warm moist air, while the horse latitudes are often sunny because of the falling cool dry air. You'll get becalmed and have to eat your horses in both places, though.

So you're saying I should live at the equator

Surely this is proof that the earth is flat. /s

Why do they all spawn from Africa?

(I get that they don't literally spawn from Africa but there origins tends towards Africa on both sides of the earth)

It borders two oceans. The northern hemisphere pacific ‘canes start from Asia

So does South and North America.

Edit 1: In other words why don't we have hurricanes form off the coast of California heading towards China and Brazil heading towards Africa?

Edit 2: I see now that I north America they form off from Mexico but South America is strangely absent.

It has mostly to do with water temperatures. Tropical cyclones need at least 27°C. Then, tjey can't form too close to the equator due to coriolis force. Some addittional factors play a role, that leave these areas.

Note: It shows December temperatures, meaning that the northern hemisphere oceans would be warmer in actual hurricane season.
