EARTH SCIENCE FACTS - Explorit Science Center


Earth not only orbits the sun but spins on its own axis as it does so. At the equator the Earth is spinning on its axis at a speed of about 1,038 miles (1,670 kilometres) an hour. Earth's spin or rotation is a relic of its origin as a hot, spinning mass when it was first formed. Earth science or geology is the science of the Earth.

Coal - Wikipedia


Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
