AVALANCHES

An Avalanche is when snow gets forced down the side of a snowy mountain. They happen without warning and usually result in death. They can reach speeds of up to 200 kilometres an hour, and kill around 200 people each and every year.

The biggest recorded avalanche in the world so far, was in Peru, and happened in 1970, killing a massive 10,000 people. I learnt how to time a power point, and how to set up really cool animations for pictures and movies. It was a lot of fun. There are three different types of avalanches. A wind avalanche is where the snow gets blown down the side of the mountain. Hard slab avalanches are when snow builds up over time, and then the top layers break off, leaving old hard snow behind. These avalanches happen in these conditions; after a fresh snowfall, in high winds, or in a snow storm.

If you get caught in an avalanche, but hopefully not, here are some tips to help you out. First of all, try swimming to the side, or away from the middle of the avalanche. The middle is the strongest part, and could easily pull you under. Secondly, if you are trapped people say it is best to push all the snow surrounding you away from you, then creating an air pocket. Once you have done that you can begin scratching at the surface.

VOLCANOES

I learnt that volcanoes have a magma chamber buried far underneath them, which holds all the lava before it erupts. Volcanoes have little volcanic cones that perch out of them and erupt smaller amounts of lava. The god of volcanoes is Vulcan, the Greek god.

COMPUTERS

I learnt how to add animations to slides, and transitions. It was fun adding animations to movies and pictures. I also added timing and background music.
