Answer:
Greenhouse effect
Explanation:
Greenhouse effect is the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Answer:
Population density.
Explanation:
Population density is a statistical data that allows graphing the number of people living in a given territory, dividing the number of inhabitants of that territory by its size, usually in square kilometers or square miles.
Thus, the more the population increases in a territory, the more its population density will increase. An example of territories with a high population density is Hong Kong, with about 7,000 inhabitants per square kilometer, while an example of a nation with a low population density is Canada, with 4 inhabitants per square kilometer.
The migration of the Moon away from the Earth is mainly due to the action of the Earth's tides. The Moon is kept in orbit by the gravitational force that the Earth exerts on it, but the Moon also exerts a gravitational force on our planet and this causes the movement of the Earth's oceans to form a tidal bulge.
For continental U.S. the answer is never. Since the earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the su, one would have to be less than 23.5 degrees above or below the equator to have the sun pass direclty overhead
Yes, things such as polluting the air with fossil fuels (not natural) and things like building factories or something as simple as throwing garbage in the oceans have a major affect. everything is like a butterfly effect, one small action can have a drastic outcome. people now a days are inventing numerous amounts of things and damaging our ecosystems. as the years go on and things like this keep happening, our world will start to get hit with those outcomes. right now we are experiencing them, with hot temperatures and less fish in the ocean and polar ice caps melting.
