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!
<h2><u>Answer:</u></h2>
Marine protection is driven by the showed negative impacts being found in our condition, for example, species misfortune, living space corruption and changes in biological community works and spotlights on restricting human-made harm marine environments, reestablishing harmed marine biological communities, and saving powerless species.
Human effects on marine biological systems. Human exercises influence marine biological systems because of contamination, overfishing, the presentation of obtrusive species, and fermentation, which all effect on the marine nourishment web and may prompt generally obscure ramifications for the biodiversity and survival of marine living things.
Between New Year's and Memorial Day, at middle latitudes in the Northern Hemisphere, the length of the day increases.
The northern hemisphere is the part of the planet that lies north of the equator. It accounts for about 90% of the world's population and most of the world's land. All of North America and Europe are in the Northern Hemisphere. Most of Asia, her two-thirds of his in Africa, and her ten percent in South America are also in this hemisphere.
This is because the hypothetical axis of the Earth does not move straight up and down, it is tilted 23.5 degrees. The movement of the Earth around this axis causes changes between day and night. During the Northern Hemisphere summer, daylight hours increase as you travel north.

New crust forms AT OCEAN RIDGES. The correct option is D.
Middle ocean ridges are the boundary that occur between tectonic plates and they are the locations where the plates move away from each other. At the edges of the ridges, magma from the underneath mantle erupts, cools and become solidified, thus forming new ocean crust.
