Did you know:
The earth is 92.9 million miles from the sun and that the moon is a natural satellite.
Did you know: The earth has 5 main motions?
- it rotates daily on its axis;
- it revolves annually around the sun;
- it precesses, or wobbles, somewhat like a spinning top;
- it follows the sun in the sun's travel through the Milky Way, and
- it moves with the Milky Way as the entire galaxy travels through the universe.
Did you know:
The earth's magnetic field reverses periodically?
- The reasons are unknown, but geological evidence indicates the strength of the field gradually grows weaker, reaches a minimum or disappears entirely, and builds again in the opposite direction, resulting
in a reversal of the north and south magnetic poles. Science estimates such reversals occure about once every one-half to one million years. The last such reversal was 700,000 years ago.

Did you know: Deserts occupy between 15 and 20% of the earth's land surface. There are almost no clouds over a desert, causing the sun to bake the sand and prevent life.
Daytime summer temperatures range from 100 to 120 F while nighttime temperatures range near 70 F in the summer and below freezing in winter.
Forest
A forest is a dense growth of trees in a large area living with other plants such as shrubs, herbaceous plants, mosses, lichens, fungi, bacteria, insects, birds, mammals, and other animals. Some have been made into National Parks, such as Sequoia in California. There are 5 types of forest:
- Coniferous - mainly made up of cone-bearing trees, also called softwoods; trees include
cedars, firs, hemlocks, pines, spruces, and tamaracks; thrive mostly in North America, Europe, and Asia; in Canada, they're called boreal and in Eurasia, they're called taiga.
- Deciduous - mainly made up of hardwood trees, that in all but a few instances shed
their foilage at the end of each growing season; broad leaved trees include ashes, birches, beeches, elms, hickories, maples, oaks, and poplars.
- Mixed - a combination of both hardwood and softwood trees.
- Tropical Rain -
commonly called jungles, these forest consist mainly of tropical hardwood and softwood trees; largest rain forest in the world are located in the Amazon basin of South America; Africa's Congo basin; and Southeast Asia, including Indonesia.
- Other -usually small, these are called scrub or thorn forests.
Did you know:
Forest cover about 30% of the earth.

Did you know:
Some large bodies of water that are really lakes are commonly called seas such as the Dead, Aral, Caspian, and Salton. The Dead Sea is really a lake and is 1,312 feet below sea level while Lake Tricaca lies about 12,510 feet above sea level.
