Question
Read thoroughly please.You are employed by Interplanetary Vacation Planners. Aliens from another galaxy have hired your company to plan their trip to our solar system. They are only interested in visiting terrestrial planets and only have the time and funds to visit one. Your job is to prepare an essay that will help them choose the planet they most want to see.
Task: Prepare a report that describes EACH planet's lithosphere, hydrosphere, atmospheres, and biosphere. The aliens who have commissioned the report have given you no guidelines, so it's up to you to decide the best way to organize your essay. In addition to learning about each planet's subsystem and spheres, the aliens will expect a summary of each planet's mass, size, distance from the Sun, length of day and year, and temperature extremes.
You must include all parts to receive full credit.
Explanation / Answer
See link from NASA! http://www.nasa.gov/audience/foreducators/topnav/materials/listbytype/Our_Solar_System_Lithograph_Set.html Lithosphere The lithosphere is the solid, rocky crust covering entire planet. This crust is inorganic and is composed of minerals. It covers the entire surface of the earth from the top of Mount Everest to the bottom of the Mariana Trench. Hydrosphere The hydrosphere is composed of all of the water on or near the earth. This includes the oceans, rivers, lakes, and even the moisture in the air. Ninety-seven percent of the earth's water is in the oceans. The remaining three percent is fresh water; three-quarters of the fresh water is solid and exists in ice sheets Biosphere The biosphere is composed of all living organisms. Plants, animals, and one-celled organisms are all part of the biosphere. Most of the planet's life is found from three meters below the ground to thirty meters above it and in the top 200 meters of the oceans and seas. Atmosphere The atmosphere is the body of air which surrounds our planet. Most of our atmosphere is located close to the earth's surface where it is most dense. The air of our planet is 79% nitrogen and just under 21% oxygen; the small amount remaining is composed of carbon dioxide and other gasses. All four spheres can be and often are present in a single location. For example, a piece of soil will of course have mineral material from the lithosphere. Additionally, there will be elements of the hydrosphere present as moisture within the soil, the biosphere as insects and plants, and even the atmosphere as pockets of air between soil pieces.
