Cause of movement of plates
Convection Current
2 types of tectonic plates
Oceanic and Continental Crust
Provides the driving force for the movement of tectonic plates
Convection Zone
Geological region where two tectonic plates collide, and one plate slides beneath the other
Subduction Zone
Where does Convection Current happen?
Earth’s mantle/Asthenosphere
Non-renewable Energy contributes to the _____
Increase of green house gas in the atmosphere
Sustainable energy
Renewable Energy
Examples of Non-Renewable energy
Coal, Fossil Fuel, Nuclear
Examples of Renewable energy
Hydro, Solar, Wind, Geothermal
“Geo” means?
Earth
“Thermal” means?
Heat
Geothermal Energy derived from the ______
Center of the earth
Heat is ____ and ____ for _____
Heat is captured and harnessed for electrical power generation
What is Geothermal Energy used for?
Heating, cooling, sources of electricity
Why when you dig a hole straight down into the earth, you would notice temperature getting warmer the deeper you go?
The inside of the earth is full of heat. This heat is called Geothermal Energy
Primary energy power plants source in many geothermal
Steam
Cools the condensed steam (water) after it has passed through the turbine
Cooling Tower
Deeply drilled wells that extract hot water or steam from underground geothermal reservoirs
Production Well
Rotating machine that converts kinetic energy of the steam into mechanical energy
Turbine
Converts mechanical energy from the turbine into electrical energy
Generator
Explain the process of Turbine and Generator
Turbine converts Kinetic energy from the steam into Mechanical Energy then the Generator will convert Mechanical Energy into Electrical Energy
Used to return cooled water (or brine). back into geothermal reservoir, maintaining minimizing reservoir pressure and environmental impact
Injection Well
Carries the generated electricity from the power plant to the grid for distribution to consumers
Transmission lines
What are the 7 processes of Geothermal Energy?
Production Well, Steam, Turbine, Generator, Cooling Tower, Injection Well, Transmission lines
How do volcanoes form?
Volcanoes form when melted rock called magma rises from deep inside the Earth through openings in the ground. Over time, this magma builds up and forms a mountain. When the pressure is too much, the volcano erupts, spilling lava and ash.
