Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Magma is molten rocks beneath the earth's crust. Hot springs are heated geothermally by underlying magma.

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. The force that generates wind is called as Pressure gradient force.

Kelvin temperature scale is the temperature scale that is based upon absolute zero.

The strength of an electromagnet can be increased by increasing the cross-sectional area, increasing the number of turns, increasing current supply, increasing the length of the coiled wire.

Sound waves cannot be transmitted through vacuum.
