Tropical places are hot because the humidity coming from the moisture of the plants and water are heated by the sun on the top layer of the tropical zone. The climate varies little in rain forest. There are five layers in the tropic trees so it's so thick that barely any light come through. This is also why vines grow up the trees so they can reach the sunlight to get nutrients. Also, the tropics are near the equator and that also causes the heat. The polars are cold because they barely get any sun heat to melt the snow or warm it up. The polars are melting due to certain chemicals and gasses in the atmosphere. also known as global warming. Hope that was helpful!

<h3>Peruvian adaptations to their physical environment</h3>
Explanation:
The Peruvians adapted to their natural environment of high altitude mountains like the Andes. The mountains created environmental challenges like low temperature, decreased precipitation, poor thin soil etc.
The Peruvians utilized the mountains in the most sustainable and efficient way both for agriculture as well as irrigation purposes. They followed terrace agriculture along the high mountain regions and built aqueducts to supply water for drinking and irrigation.
The agricultural terraces were constructed in such a way it received a good amount of sunlight even though sunlight was blocked by the surrounding high mountains. The crops were spaced widely to ensure proper sunlight and crop growth.
The irrigation system through aqueducts was constructed to prevent flooding.
