Answer 1

Answer:

Ans 1 Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.

Ans 2 Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers.

Ans 3 Today, burning of wood is the largest use of energy derived from a solid fuel biomass. Wood fuel can be used for cooking and heating, and occasionally for fueling steam engines and steam turbines that generate electricity.

Ans 4 Fossil fuels are formed over a timescale that is not useful to people, requiring particular conditions and millions of years. ... Oil as fuel for transport and a base in a huge array of products means it in unlikely to be easily replaced, meaning our fossil fuel dependency will likely mean using them to exhaustion.

Ans 5 The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal - also known as thermal coal - is mainly used in power generation.

Ans 6 Coal is a fossil fuel that formed around 400 million years ago. Coal can be called "buried sunshine" because the plants used photosynthesis to collect energy from the sun to develop compounds that created plant tissues. When coal was formed, the earth was covered with swamps.
