Glacial eruptions Study guides, Revision notes & Summaries

APES: Unit 2, Ecological Tolerance and Natural Disruptions to Ecosystems Natural Disruptions to Ecosystems - correct answer Changing Sea level due to the amount of glacial ice on Earth overtime, major environmental change/upheaval leading to habitat change, wildlife engaging in short term and long term migration for a variety of reasons (like natural disruption) Limiting Factor Principle - correct answer Too much or too little of any abiotic factor can limit or prevent growth of a population...

When did global warming start? - -From 1950s Three ways of knowing climate change? - -Ice cores, glacial retreat, early spring and rising sea levels Describe the greenhouse effect - -The earth allows short wavelength radiation from the sun to heat up the earths surface. Some of the radiation (long wavelength radiation) is emmited and reflected by the earth and is absorbed by greenhouse gases like nitrous oxide, methane and sulfur dioxide This heats up the earths surface What are the greenh...

Geomorphology study of the shape of the Earth's features and how they change over time Present era of timescale Cenozoic era Radiometric dating rate of radioactive decay of rock elements to determine the age of rocks Timescale for geologic change history of the Earth since its formation as spanning a single 24 hour day, long time frame, relatively short period of evolving life forms Endogenic internal processes such as volcanic and tectonic activity Exo...

Age of Earth 4.6 billion years Seismometer Instrument used to measure horizontal or vertical motion during an earthquake. Uniformitarianism The past geological events can be explained by forces occurring today Alfred Wegener A German scientist who proposed the theroy of continental drift Geologic evidence of continental drift -rock units on different continents have similar structure Mid Ocean Ridges -submerged mountain regions -longest continuous feature of the earths crust -tensio...
