If you lived on Mars and observed the solar system from there, would describe retrograde loops, would always be seen near the sun, and would never be visible as crescent phases. (We are limiting responses to the five planets you could see with the naked eye from Mars, which are Mercury, Venus, Earth, Jupiter, and Saturn.) Hint: From Earth, all the other planets show retrograde motion; Mercury and Venus are always near the sun; and Mars, Jupiter, and Saturn are never visible as crescents.

Sedimentary rock formation occurs when igneous, metamorphic, or other sedimentary rocks are exposed to the unyielding forces of nature found on the earth's surface. the formation of sedimentary rock occurs by several processes over millions of years. when rock sediments are deposited, an increase in weight causes pressure to increase which leads to the compaction of the rock particles. water is pushed out and cementation occurs as dissolved minerals are deposited in the very small spaces between the rock sediments acting as glue that binds the sediments together. which process describes the changing of sediments into rock by compaction and cementation? a) deposition b) lithification c) physical weathering d) chemical weathering
