Land breezes and sea breezes are both types of local wind patterns that are caused by the temperature difference between land and water. During the day, land heats up more quickly than water, creating a low-pressure area over the land and a high-pressure area over the water, resulting in a sea breeze blowing from the water to the land. At night, the land loses heat faster than water, creating a high-pressure area over the land and a low-pressure area over the water, leading to a land breeze blowing from the land to the water.

The earth is a planet and the sun is a star. The star was born before the planet from a much larger resources called a nebula. The hydrogen heats up and becomes sensed. This creates a stars. These stars generate gravity which caused debris from the big ban to orbit the star as it grew larger. Then the debris practically banged into eachother creating asteroids and comets. These asteroids and comets fused together creating moon size planets. Then those banged together to create a dwarf planet earth. Dwarf earth then joined with other dwarf planets to make. That's it in very simple terms. Comparing a planet and a star is like comparing an apple to a leaf.

The Auroras is collision that occurs during the Northern lights when active sun particles hit the earth's atmosphere. Auroras can be seen every year in the north and south pole hemisphere in an array of colors including pink, light green, yellow and blue.

The main problem with drought is the affect on agriculture. This could be very much mitigated if the water table was more than replenished. Every once in a while the Missouri river goes into flood stae and vast quantities of water flow uselessly down into the ocean wrecking things down stream on its way. This is foolish. If a very deep, wide hole were dug down to well below the water table inland and filled with clean stone, it could provide a conduit to pump flood water into in order to replenish the water table. This would be a major advantage to every one concerned, up and down stream.
So far as tropical droughts are concernd, droughts could be often prevented in the first place if termites were eliminated that eat the mulch cover over the soil. This mulch aids considerably in water infiltration and even acts to store water itself as opposed to running uselessly into the ocean over vast areas. You may see an article that explores what I believed happened to the earth when termites first evolved in the Permian era in http://www.angelfire.com/nc/isoptera/roach.html and http://www.angelfire.com/nc/isoptera/permian.html .

No, rainbows require water droplets and sunlight to form, which are not present in space. The colors we see in space are due to various processes such as the dispersion of light through gases and dust, or the emissions of different elements.

September 22-23 & March 21-22. They mark the beginnings of autumn and spring respectively, in the northern hemisphere. They mark the beginnings of spring and autumn, respectively, in the southern hemisphere.
The Spring equinox and the Autumnal equinox occur when the length of daytime and the length of nighttime are exactly equal to each other.

There are several astronomical observations which support the Big Bang theory. First of all, the universe is expanding. That can be measured by observation of the Doppler shift in radiation emitted by various stars, galaxies, quasars, etc. Furthermore, the more distant any given astronomical object is, the more rapidly it is receding from us. This is consistent with the expected result of the Big Bang. Secondly, we have observed what is known as the cosmic background microwave radiation. The sky is filled with radiation, no matter in what direction you look, and it corresponds to the radiation that would be emitted by an object at a temperature of about 4 Kelvins. This is also consistent with the expected residue of the Big Bang, 13.8 billion years later (the universe has cooled off a lot, in that time). It is also possible to assess the chemical constituents of the universe, the quantities of hydrogen, helium, and other elements, which can be observed by spectrographic analysis, and again, the results are consistent with the Big Bang theory. Everything fits.

Betelgeuse is in the constellation Orion and is best seen during the winter months in the northern hemisphere. It is very well placed for viewing around the months of November, December and January. Orion is a very easy constellation to find and Betelgeuse is the very bright and reddish looking star at the top left of it.

Any constellation is a group of stars that appear to form some kind of pattern,

but have no connection with each other. They all happen to be in roughly the

same direction from us, but they're all at different distances. So there's no

such thing as a constellation's distance from us.

Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another.

(It is between 3.5 and 5.5 on the Mohs hardness scale)

The state where the sunrise is seen first in the United States is Maine. Due to its easternmost location in the country, particularly at West Quoddy Head, Maine is where the sun rises earliest in the United States.

A synodic month is the time it takes for the Moon to return to the same phase, such as from full moon to full moon. This period is approximately 29.5 days long. It differs from the sidereal month, which is the time it takes for the Moon to complete one orbit around the Earth.

The Earth needs the sun for several reasons. 1. Plants/Trees need sunlight to live, and plants give us oxygen 2. Several research projects showed that human beings need a specific amount of sunlight to function properly. 3. If this planet did not see a sun, it would be too cold for life to live on. I am sure that there are other reasons, but those are some pretty important ones.

The Moon orbits the Earth from west to east. Its apparent motion is from east to west because of the rapid rotation of Earth compared to the monthly orbit of the Moon. Since the Moon orbits from west to east, its once monthly rotation is also from west to east, because it keeps the same face (mostly) toward the Earth throughout the month.

In plain English: counter clockwise, as viewed from above the north pole.

A space station is a large spacecraft that orbits Earth and serves as a home and workspace for astronauts. It is equipped with living quarters, laboratories, and communication systems to support scientific research and experiments conducted in microgravity. Examples include the International Space Station (ISS) and China's Tiangong space station.

The polar opposite of frogs could be something like desert creatures, such as scorpions or snakes, as they inhabit different environments and have different characteristics.

It is because the earth rotates on its axis. In ancienct times philosophers believed the sun revolved around the earth but that was wrong. The earth actually rotates and so when it is rotating, about only 1/2 of the planet is facing the sun. The earth tilts on its axis and this makes summer and winter. When the northern side of the planet tilts towords the sun, then the days in the north are longer, and the night is shorter. Things are weird at the north and south pole; they have night for several months at a time, and daylight for several months at a time, depending on the earth's position in its orbit. Imagine what it would be like to have the sun in the sky for months without setting!

A variable star (or pulsating star) is a star that an earth observer sees as changing in luminosity over time. This variation in brightness may be something the star is "doing itself" because of changes in its nucleosynthetic processes, or it may be due to the passage of dust clouds or the like between the star and the observer. Wikipedia has more information, and you'll find a link to their post below.

ABOUT 40,000 km from the Earth
it surrounds the earth.

· Angiosperms live in all terrestrial and aquatic habitats on earth. Except for conifer forests and moss-lichen tundras, angiosperms dominate all the major terrestrial zones of vegetation.

· The angiosperms environment is a hot, tropical, and wet places, they could live almost anywhere except if the place is cold or has no water or no sunlight.

The first one that succeeded in achieving orbit was Sputnik-1, launched by the USSR

from the Baikonur Cosmodrome in Kazakhstan on October 4, 1957.

There were earlier attempts that failed, in both the US and Russia. Sputnik was

the first one that achieved orbit outside the atmosphere and stayed up there for

a while.
