The color of a planet provides clues to its composition. From space, much of Earth looks blue because most of its surface is covered with water. The surface of Mars is much different from that of Earth. Much of its surface is made up of iron oxide, or "rust." Which color would you expect Mars to be?

Mars would have different variations of brown, red, and orange.

Explanation:

Since different places of Mars have different substances or have different "ages" the color will be different.

Rust is formed because iron reacts to different substances, so there might be different weather patterns around Mars, and hence different colors of the rocks, iron, etc.

Hope this helps:)

Sorry just a 4th grader :(

I think this is correct though

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
