Earths deep subsurface - Study guides, Class notes & Summaries

North American and Eurasian plates are moving apart from one another and creating the mid-atlantic ridge. This is an example of what type of plate boundary. Divergent Tectonic plates move slowly across the asthenosphere on convention currents Forms when pre-existing rock is subjected to high temperatures, pressure or chemicals Metamorphic Forms when existing rock is weathered and deposited as small grains Sandstone Forms when magma cools and hardens Igneous ...

Environmental Science Energy Unit All Answers Correct 2024 Describe the process by which electricity is commercially generated. Normally produced by the rotation of an electromagnet inside numerous wire coils. The rotation of the electromagnet is accomplished by using a turbine turned by steam, water and wind. Explain why no form of electricity generation can be over 100% efficient. Energy is lost during each transformation, usually as heat. To turn the energy of falling water into...
