hypothesis - proposed explanation for an observed phenomenon, which can be rigorously tested using the scientific method (may be regarded as a prediction) theory - supported by a number of testable statements and used as a general principle to explain a phenomenon; intended to be accurate. predictive models of the natural world Theory of Plate Tectonics - proposed explanation by Alfred Wegener of the formation of the continents first as a Pangaea supercontinent then Laurasia and Gondwanalan...

Ecosystems - refers to living organisms and the physical and chemical factors which influence them Habitat - a place where organisms live Population - organisms of the same species, usually defined as living in the same area

Explain how tectonic processes lead to the formation of an underwater volcano - divergent plates / description ; hot gases / molten rock / lava / magma + rises / erupts ; lava cools / solidifies / hardens to form rock ; Describe the mutualistic relationship between these algae (zooxanthellae) and the coral. - any 3 of: algae photosynthesise ; produce oxygen / glucose / sugars / carbohydrates / organic compounds / amino acids for coral ; corals provide protection for algae ; corals pr...

What is 1/2 of the energy from the sun used for? - Evaporation - Converting water from liquid to gas

El Nino - large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific; June-December; caused by a change in wind patterns La Nina - Trade Winds are particularly strong in carrying warmer water westwards across the Pacific leading to colder than average temperatures in the east and warmer than average temperatures in the west; Effects of La Nina - - Stronger winds along the equatorial region...
