Connection of 2 Green Book Climate Labs

In Activity One we learned about heat absorption in water, light soil, and dark soil. Dark soil heated up the quickest and gradually dropped temp. Water took longest to heat up but kept its heat the most. Light soil was in between both during heating up and cooling down. I knew the dark soil would heat up the fastest but i was clueless on how the water would react at all.

Activity Four, was on how the climate heated up with the Dark soil A, Dark Soil with Clouds B, Light Soil C, Light Soil with Clouds D, Water E, water with clouds F. The results where close to Activity 1 except the ones with clouds had an increase in temp. I got the data i excpected since i knew prior to this about the basics because of Activity 1.

The Small scale labs where a very good example of how Earth's climate works. It helped me understand how in different parts of the world would have a certain type of climate based on their soil and if they had clouds. The climate with light soil and no clouds would resemble drought the most. It has heat but not too much and during the night it gets really cold because there isn't any moisture or clouds in the air to keep the warm in.

Drought

INTRODUCTION

A Drought is a climate that has a shortage of water for an extended period of months and years. Rain rarely ever falls in a climate that has a drought. A drought can turn fertile land into a massive desert.

This is a picture of how droughts remove water quickly and how the land drys fast as well.

WHERE AND WHY

Droughts happen around the equator where water evaporates very quickly and where it is hot and dry. Some places that have droughts are India, US, Brazil, Iran, West Africa, South Afrcia, Eastern Europe, Western Asia, and Australia. Droughts happen because a region recieves belowaverage precipitation. Some of the World's droughts are shaped by cycles like El Nino and La Nina. It is predicted by the National Center for Atmospheric Research that in the future droughts will increase in intensity and the percentage of Earth's land area that has droughts will double in size.

This is a picture showing droughts. Dark purples and greys are at risk of droughts. Blues are where droughts are least likely to have a drought.

WEATHER CONDITIONS

Some of the weather conditions needed for a drought to happen are low to no water. This low amount of precipition causes the soil to dry out in a land that already has very little water. When droughts occur the risks of wildfires increase.

The top map shows where droughts were reported and the bottom map shows the people who were affected by the droughts.

TECHNOLOGY

Scientist use Case Studies to help predict droughts and how the predictions are communicated to a society. Computer-based simulations have been used to track areas of persistant dryness of the past to help predict where they might occur in the future. These models do not agree on which areas will be at risk the most.

ENVIRONMENTAL IMPACT

Droughts have a big impact on people and the environment. The greatest impact on the environment would be the decrease in plant life and animals because of the dryness not being able to support life. The impact on the people is that water is really hard to find and this climate doesnt allow life or human beings to survive. People would have to move out of an area of drought to places with more water.

WARNINGS

Warnings for droughts are issued by governmental figures in a society and relayed down the ladder to other groups of people who may be endangered. Droughts are a slow climate change so relaying a warning in a society wouldn't be hard to do.
