Q3 - SCIENCE (Formation of Volcano, Convection Currents, Renewable/Non-renewable, Geothermal Energy)

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.
