extensive drainage system that is made up of conduits. This was discovered by
the archaeologists in the town of San Lorenzo, the largest city of Olmec
cities. These was carved into a U type shape and covered by capstones. This was
believed to be used as aqueduct to provide water throughout the cities.

civilizations to be the first to have their own writing system in America. Their
writing is mostly symbols rather than letter representation.

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!
