A cloud is a large group of tiny water droplets that we can see in the air. Clouds can contain millions of tons of water. Clouds are formed when water on Earth evaporates into the sky and condenses high up in the cooler air.
Rain, snow, sleet and hail falling from clouds is called precipitation. Most clouds form in the troposphere (the lowest part of Earth’s atmosphere) but occasionally they are observed as high as the stratosphere or mesosphere.
There are a range of different types of clouds, the main types include stratus, cumulus and cirrus. Stratus clouds are flat and featureless, appearing as layered sheets. Cumulus clouds are puffy, like cotton floating in the sky. Cirrus clouds are thin and wispy, appearing high in the sky.
There are many variations of these 3 main cloud types including stratocumulus, altostratus, altocumulus, cirrostratus and cirrocumulus. Fog is stratus type of cloud that appears very close to the ground.
Clouds can also be made of other chemicals. Other planets in our Solar System have clouds. Venus has thick clouds of sulfur-dioxidewhile Jupiter and Saturn have clouds of ammonia.

Lightning is a powerful burst of electricity that happens very quickly during a thunderstorm. Lightning is caused by an electrical charge in the atmosphere that is unbalanced. The movement of rain and ice inside a thundercloud creates an electrical charge, with the negative charge (electrons) forming at the bottom of the cloud and the positive charge (protons) forming at the top.Opposites attract so the negative charge at the bottom of the cloud seeks out a positive charge to connect with.
Lightning is usually produced by cumulonimbus clouds that are very tall and dense. Lightning can occur inside clouds, between clouds and from clouds to the ground. Around one quarter of lightning is from cloud to ground. There are bolts of lightning striking somewhere on Earth every second. Most lightning occurs over land rather than oceans, with around 70% of it occurring in the Tropics. Lightning strikes usually last around 1 or 2 microseconds. Lightning contains millions of volts of electricity. The average temperature of lightning is around 20000 °C (36000 °F).
When lightning strikes the ground it seeks out the shortest route to something with a positive charge, this might be a tree, a tall building or if they’re very unlucky, a person. Thousands of people are struck by lightning every year. Direct lightning strikes are usually fatal. Lightning rods (also called conductors) are metal rods or similar objects that divert lightning safely to the ground, they can often be seen at the top of tall buildings.
Thunder is the sound caused by lightning. Lightning can also occur during volcanic eruptions, dust storms, snow storms, forest fires and tornadoes. The study of lightning is known as fulminologywhile astraphobia is the fear of thunder and lightning.

A rainbow is a multi-colored arc that forms in the sky. Rainbows are created by both reflection and refraction (bending) of light in water droplets in the atmosphere, which results in a spectrum of light appearing. A rainbow is not an object, it cannot be approached or physically touched.
A rainbow is in fact a full circle of light. However, due to most people viewing a rainbow on the ground we only see a semi-circle or arc of the rainbow. A rainbow is not situated at a specified distance, instead it will always be visible to a person at the precise angle freshwater droplets reflect the light which is 42 degrees in the opposite direction of the sun. No two people see the same rainbow, in fact even our individual eyes see slightly different rainbows. If someone appears to be standing under a rainbow you can see, they will see a different rainbow at the same angle but further away.
Rainbows can be seen not just in rain but also mist, spray, fog, and dew, whenever there are water drops in the air and light shining from behind at the right angle. A “double rainbow” is where a second, much fainter arc can be seen outside of the primary arc. This is caused by the light reflecting twice inside the water droplets. As a result of this double reflection the colors of the second arc are inverted with violet on the outer edge and red on the inner edge. A “moonbow” is a rare lunar rainbow or night time rainbow produced by light from the moon. Our eyes see it as white even though all colors are faintly present. A “fogbow” is formed by cloud and fog droplets, they are almost white with very faint colors visible. Fogbows are quite large and much broader than a rainbow.
