Thunder Lightning: Thunder Lightning is a sudden, shocked, and very fast electric force between the cloud and ground, or between clouds. The speed of thunder can be several miles long. It is so hot, with average temperatures of 34,000 ° Celsius, that cause surrounding air suddenly expanding with a loud explosion and sounds. This is why sometimes we can hear thunder. The most dangerous type of cloud caused by lightening is called cumulonimbus, When the cloud rises high enough, the moisture freezes and creates crystal ices and snowflakes. It began to fall, pushing the rain on the way down. This is more humid, rainy air, and it is the friction between those who generate static electricity. When the cloud is fully charged with electricity, it will burst as a flash of lightning. So lightning suddenly appears before the rain and the sounds are very loud., Kangaroo: Kangaroo is an animal found only in Australia. Kangaroos eat grass and plants. They have short front legs, but very long and very strong back legs and a tail.
