Mesosphere
equa means half of the earth, and equator means an imaginary line in the middle of the earth. b****! jk! (8
You couldmake the solar system orshow the earth @ the bottom, divide background in half & paint half sun half moon
Assuming the earth is a sphere, it corresponds to the rule that M is proportional to radius^3 - shrinking the radius by half, we see: (1/2)^3 = 1/8, the earth has shrunk to a mere eighth of it's mass.
Dinosaurs were the one who dominated the earth
The Equator is an imaginary line on the Earth's surface equidistant from the North Pole and South Pole that divides the Earth into a Northern Hemisphere and a Southern Hemisphere. an imaginary line dividing the earth in half horizontally ^ The Equator is an imaginary line on the Earth's surface equidistant from the North Pole and South Pole that divides the Earth into a Northern Hemisphere and a Southern Hemisphere. The band around the middle of the Earth, separating the northern from the southern hemispheres. Earths equator is an imaginary line equally distant from both Pole's. It goes horizontally around Earth's middle. ^ It is also the point where both 0 degrees latitude and longitude orginate.This areas also reseives the most sunglican anually and is home to a region referred to as the Tropics.
The upper half of the middle atmosphere is known as the mesosphere. It extends from about 50 to 85 kilometers above the Earth's surface. Temperatures in the mesosphere can reach as low as -90 degrees Celsius.
The middle number in the upper half will be three-quarters of the way up and is known as the upper quartile.
The northern is hemisphere is just the north upper half of the Earth. So it is the upper half of the Earth
stratosphere
Stratosphere
It the earth was half its mass, then it might only be able to hold half the atmosphere. In this case, it may not be able to maintain many species of life as we know it.
because of gravitational pull
The surface of the upper half or the lower half of the Earth as we usually envision it.
Nitrogen compromises half of Earth's atmosphere, with oxygen making up most of the rest. Both nitrogen and oxygen are essential gases for supporting life on Earth.
The planet that is half the size of the earth, has 2 moons, and has an atmosphere of mostly carbon dioxide is Mars. The average length of a day on Mars is 37 minutes longer than that of the Earth.
The ionosphere is located approximately in the same region as the top half of the mesosphere and the entire thermosphere in the upper atmosphere, from about 40 mi (60 km), continuing upward to the magnetosphere.
The http://wiki.answers.com/earth/Atmosphere/overview.htmlis divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space.1) The http://wiki.answers.com/earth/Atmosphere/troposphere.htmlis the first layer above the surface and contains half of the Earth's atmosphere. http://wiki.answers.com/earth/Atmosphere/weather.htmloccurs in this layer.2) Many jet aircrafts fly in the http://wiki.answers.com/earth/Atmosphere/stratosphere.htmlbecause it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.3) Meteors or rock fragments burn up in the http://wiki.answers.com/earth/Atmosphere/mesosphere.html.4) The http://wiki.answers.com/earth/Atmosphere/thermosphere.htmlis a layer with auroras. It is also where the space shuttle orbits.5) The atmosphere merges into space in the extremely thin http://wiki.answers.com/earth/Atmosphere/exosphere.html. This is the upper limit of our atmosphere.
