Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels, which increases greenhouse gas concentrations in the atmosphere.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas, that are burned for energy.

Front

What is the highest energy coal type?

Back

Anthracite is the type of coal with the highest energy content, known for its high carbon content and heating value.

Front

What is metamorphic rock?

Back

Metamorphic rock is a type of rock that has been changed from its original form (sedimentary or igneous) through heat, pressure, or chemically active fluids.

Front

What is renewable energy?

Back

Renewable energy is energy that is collected from resources that are naturally replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the focus of an earthquake, where the seismic waves are first felt.

Front

What is the focus of an earthquake?

Back

The focus (or hypocenter) is the point within the Earth where an earthquake originates, and seismic waves radiate outward from this point.

Front

What is solar energy?

Back

Solar energy is energy harnessed from the sun's rays, which can be converted into electricity or heat.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed by the accumulation and compaction of mineral and organic particles, often found in layers.

Front

What is the process of recycling?

Back

Recycling is the process of converting waste materials into reusable materials to reduce waste and conserve resources.
