Friday, 28th of February

In today's class, we started talking about some of the questions we asked the other day in the test to clarify some concepts.

Next, we have continued talking about the atmosphere. Today, we started with the layers of the atmosphere  that are the followings:

➼ TROPOSPHERE: (Is the closest to us.)

➼ STRATOSPHERE: (Atmosphere ozone is concentrate in this layer.)

➼ MESOSPHERE: (Lowest temperature value in the atmosphere.)

➼ THERMOSPHERE: (Density much nearer vaccum.)

During the second hour, we started talking about the Greenhouse Effect that is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Is a natural process. 

Finally we have done an activity in groups. Each group had one of the following topics and we had to read it and draw conclusions that we would present during the next session.

➼ Air pollutans

➼ Ozone hole

➼ Uv index

➼ Changing color of the sky

My group had the topic of air pollutans.

During today's class I felt good, and in our case I found the text that we had to read very interesting. It was very well explained.
