Name the three major kinds of rocks - Sedimentary- deposition of material at the Earth's surface and within bodies of water Metamorphic- transformation of existing rock through heat or pressure Igneous- cooling and solidification of magma and lava Has the African plate been stationary or mobile and have other plates moved towards or away from it? - Relatively stationary while other plates have moved away from it causing no collisions ad therefore no mountain chains formed. How was the A...

If 18.25 mL of an 0.0020 M iodate solution is rquired to titrate a 10.00 mL sample of vitamin C solution, What is the molarity of the ascorbic acid in the solution? correct answers The individual oceans (Atlantic, Pacific, Indian, etc.) on the earth are physically cut off from one another by land barriers that prevents the mixing of waters between different ocean basins.

Solar System - Science Olympiad Exam Questions And Answers (Verified And Updated) How did the terrestrial planets form? - answerIn the proto-Solar-Sytem, after the sun formed, the rest of the materials orbiting close around it began to clump together too. However, closer to the sun, lighter materials like gases blew away and only rocky material was left, causing the four terrestrial planets, and some of their moons, to form. What are the characteristics of Terrestrial Planets? - answerSol...
