Fossil fuels are formed from the remains of ancient plants and animals, buried deep inside the Earth for millions of years.

Over a long, long time, heat and pressure has turned these remains into the fossil fuels that we call coal, oil and natural gas. Today, fossil fuels are mined and burned to release the energy stored inside them.

Fossil fuels are widely used because there is a good supply and they are fairly cheap to mine and drill for. However, fossil fuels are non-renewable, which means that one day they will be all gone. People can't make fossil fuels!

Some uses of fossil fuels

Coal and natural gas are burned to make the electricity that we use in our homes for cooking and for heating and cooling.

They are used to power factories.

Oil is changed into petrol for cars and trucks, and into fuel for aeroplanes and ships.

Plastics are made from fossil fuels.

What's wrong with fossil fuels?

When they are burned, the carbon stored inside fossil fuels is released into the atmosphere as a gas known as carbon dioxide. Carbon dioxide is a greenhouse gas and is causing global warming.

Burning petrol (made from oil) in cars pollutes the air we breathe.

Power plants too burn oil and coal to make electricity and release poisonous gases into the air. These gases cause air pollution and acid rain.

Coal is a fossil fuel

We all love butterflies for their beautiful, brightly-coloured wings. But did you know that these fab flyers begin life as something completely different? As they grow, they undergo one seriously terrific transformation - a process known as " metamorphosis ".

Join Nat Geo Kids as we follow the life-cycle of this quirky creature, from the egg to the air!

Stage 1: the egg

It all starts when a female butterfly lays her eggs, usually on leaves or stems of plants. Inside these tiny eggs, caterpillars grow. Depending on the species, the eggs can vary in shape and texture - they can be round, oval or cylindrical, and smooth, bumpy or wrinkled. The time it takes for the eggs to hatch can also vary - in some species, they will hatch within a few weeks and in others they will only hatch once the weather is warm enough.

Stage 2: the caterpillar

Once ready, the caterpillar leaves its egg home and enters the big outside world! And these little critters have one serious appetite - they actually eat their way out of the egg and immediately start chomping on the leaves of the host plant. During this stage, they shed their skin four or five times - as the caterpillar grows, its skin becomes too tight and splits open, revealing a new, larger skin underneath. A fully grown caterpillar can be over 100 times larger than when it emerged from its egg. Wow!

Once fully grown, the caterpillar forms itself into a "pupa" (or chrysalis) - a kind of vessel in which the caterpillar changes into a butterfly. They usually do this on twigs or safe, hidden areas around the host plant. The "pupa" stage may last a few weeks to several months depending on the species. During this time, a hardened case forms around the pupa to protect it from predators and extreme weather conditions. And inside, the tissue, limbs and organs of the caterpillar transform. The result? A wonderful winged butterfly!

Once the butterfly is ready to emerge, the case around the pupa splits open. But it's not time for take off just yet, as the wings are at first wet, soft and wrinkled against its body. The butterfly waits for its wings to dry, and pumps a liquid called hemolymph into them so that they become big and strong. Once fit for flight, this brilliant bug then takes to the air in search for flowers to feed on and for other butterflies to mate with. And that's the cycle complete - and ready to start all over again!

Did you know...?

Moths also go through this process of metamorphosis. Check out the four stages of the Atlas moth, below - the largest moth in the world!

The process in which a tadpole turns into a frog is called metamorphosis, and it is an amazing transformation. Here we have broken metamorphosis down so you can see the stages a tadpole goes through as it develops into an adult. It is important to note that the frogs in the following pictures are not all the same species.

This is an egg mass laid by a frog. Each of those black dots is made up of a bunch of cells that will eventually grow into a tadpole. Depending on the species, these egg masses can be made up of several hundred eggs!

Within a few days, the eggs develop into tadpoles. Tadpoles live completely underwater. After a few weeks, a hormone in the tadpole's thyroid gland initiates metamorphosis.

Over about a 24 hour period, the tadpole develops into a frog. This means almost every organ has to change so the tadpole can go from living underwater to living on land as an adult frog. In this picture you can see the tadpole has started to grow hind legs.

After the hind legs have started to form, a pair of front legs will begin to develop and the tail will start to disappear. You might also notice that the tadpole has started to form a frog-like face. The tadpole's skull is made out of cartilage (the same stuff your nose and ears are made out of) but during metamorphosis, the cartilage is replaced with bone.

When the tadpole reaches the froglet stage, it is almost a full adult. At this point, the tadpole's gills have disappeared, and its lungs have enlarged. This means it is ready to leave the water and live on land. Once its tail disappears, it will become an adult frog.

This is a fully grown frog. As you have just read, frogs go through a lot to get to this phase. They even go through changes that aren't visible in these pictures. The tadpole's horny teeth, once used to tear up plants, disappear and tongue muscles develop to catch insects. The tadpole's large intestine, important for digesting algae and plants, shrinks to suit the frog's meat-eating diet.
Metamorphosis is quite a process. It is also when the frog is at its most vulnerable. Help give frogs a chance by starting a Bring Back the Wild Campaign to protect the Oregon Spotted Frog.

Plant Life

Plants are an important part of our world. They give us food, such as sweet fruits, healthy vegetables, and tasty nuts. Wide, leafy plants give us shade on a hot summer day. Plants also make the oxygen in our air. People and animals need oxygen to breathe.

Plants give animals a safe place to hide from their enemies. Many animals make their homes in trees and bushes. Flowering plants add color and beauty to gardens, parks, and yards. The many plants in our world make it a wonderful place to live.
