Earthquake in Japan

An Eartquake recently erupted in Japan.It was said to be the eartquake with the 7th highest magnitude.

An article about it can be found at: http://www.huffingtonpost.com/2011/03/11/japan-earthquake-tsunami_n_834380.html

I have summarised the article and it says that a ferocious tsunami spawned by one the largest eartquakes ever recorded hit Japan's eastern coast last Friday.It killed hundreds of people.

The magnitude-8.9 offshore quake unleashed a 23-foot (seven-meter) tsunami and was followed by more than 50 aftershocks for hours, many of them of more than magnitude 6.0.NHK said more than 4 million buildings were without power in Tokyo and its suburbs. Some nuclear plants were also said to be affected.

This is a real-life example of how the physical environment affects the human environment in a bad way.The result of it is leaving the people in Japan homeless,injured and even dead.
Some nuclear plants were said to be affected and this could then lead to another resulting effect on the people in Japan.The people in Japan maybe might have to look for natural resources like maybe cutting more trees.This cycle will then continue.

This is the end of today's post.We should keep the people in Japan in our prayers and try to help them in whatever we can do.

The rock cycle

What is the rock cycle?
The rock cycle is the recycling of rocks and it shows how rocks are turned into different forms of rock.


Here is a diagram on how the rock cycle works:

Sediments come together to form sedimentary rocks.The sedimentary rock then becomes a metamorphic rock under pressure.The metamorphic rock then turns into a igneous rock when it melts and cools.

*Note: The rock cycle does not alsawys follow the same pattern.

To conclude we have added a video on the rock cycle to explain more about it.
