What is one theory of the origin of the moon?
The latest theory of the formation of the Moon is that the Earth and Moon were formed by the collision and amalgamation of two smaller objects. The combined material became the Earth and the debris trail of lighter material thrown off formed the Moon. 7. What are some of the mechanisms which modify and distribute heat around Earth? (Program describes six mechanisms.) 1. Water dissolves CO2 which holds the greenhouse effect down. Volcanoes supply CO2 which maintains the effect at a friendly level. 2. Thermohaline circulation pattern of slow, deep ocean currents distributes heat. 3. Ocean tides distribute heat. 4. Surface currents circulate warm water towards the poles and vice versa. 5. Evaporation from the sea drives the water cycle. 6. Life processes fine tune the CO2 in the atmosphere. 8. Where is most of Earth’s biomass found? Most of Earth’s biomass is in the sea. 9. How many bacteria are in a drop of seawater one microlitre in size? More than a thousand bacteria are in a typical d
