You see, we are more likely to find tropical rainforest and jungles on a hot and sunny location like on the equator. In fact, desert doesnt always have to be hot at all, for instance, the antarctica. Deserts are formed on locations with different climates and less precipitation. And unlike the locations on the equator, which receives high amount of rainfalls, deserts receive way too little, thus, affecting the vegetation and growth in the area.
Tectonically stable means that this part of the continent has not moved for billions of years. The rock formation is important understanding the history of Earth since its unmoved and untouched state can provide ideas about how the Earth looked like as seen on the layers of the rock formation.
Geography would be useful planning because it helps the builders determine where certain public facilities, such as parks and restaurants, and transportation, and buildings would be located.
Troposphere is the layer where the air is thin as well as very warm
