Questions On Studying The State Of Our Earth

13) [2.1] Is there a difference in the biology of these two phytoplankton that might be related to what is happening in this lake? (Look back at the natural history if you need to.)

The affect of environmental issues occur everyday and in particular deforestation is becoming a highly ranked subject. From animals to the human race, the alacrity of trees that are cut down affects every individual in a variety of ways. Not only do people need to help the planet but they need to help themselves and further generations to come, such as children and grandchildren because these natural resources that are being taken away from society are as well shaping the future. For comprehensible reasons, forests use to make up the world, until man made creatures started to destroy and destruct the most important supply to human kind which are trees. Trees are crucial to every living entity for the reason of providing oxygen to all.

The science that is connected with planet earth encompasses geosciences or earth science among others. Containing old histories, this is considered as a part of planetary science while it possesses holistic and reductionist approaches in the science of the planet Earth. This discipline can cope with lithosphere, atmosphere, biosphere or hydrosphere. Quantitative understanding has been developed by the scientists to understand the ground systems with the tools by mathematics, physics, chronology, biology, chemistry alike that help to know how the universe is evolved.

This is how the lake keeps the water level normal and the plants and grass looking green. If it doesn’t rain, the water level in the lake goes below normal. A measuring scale is normally on the rain gauge which measures the precipitation. A rain gauge put outside to record the amount of rain. In the case of Mary Jo Peckham Park, it gets its precipitation mostly from rain. Most of the time, it rains at least some every month but in the past there has been a drought. Mary Jo Peckham Park received enough rain in 2015 and the plants are blooming, the lake is full, and the ducks are enjoying the

3. The levels of Lake Powell and Lake Mead both show steep declines in the past decade. What are the two things that control the level of a reservoir?

Why could having consumers as well as producers present change the amount of dissolved oxygen in the lake?

A local farmer notices that the level of water in the pond behind his house has been going down. Temperatures have been very high in the area, but there are also a lot of animals on his farm that may be drinking the water. What is causing the water to

Exercise Lab 1. How much does temperature vary in large and small aquatic environments? Lab 2. What determines the water clarity of lakes, rivers and oceans? Lab 3. Where does the phosphorus go? Lab 4. How does human activity in watersheds affect the quality of lakes and rivers? Lab 5. Are the Great Lakes being influenced by the global greenhouse effect? Lab 6. How is the flow of the Red Cedar River influenced by the weather? Lab 7. What is the relationship between flow and turbidity in the Red Cedar River? Page 2 4 6 8 12 15 18

Deforestation has a negative effect on our environment and should be limited. Deforestation harms animals and plants, can wipe out entire forests, and intensifies global warming. Deforestation

However, the amount of dissolved oxygen remained extremely high when adding fertilizer to the TAC, contradicting our hypothesis. This probably is because there was not algae growth in the water, so the water’s dissolved oxygen levels remained the same because the algae did not take up all the oxygen. The water turned black and foggy, however it maintained a perfect amount of dissolved oxygen. In addition, the grass died once we added the fertilizer to it, contrary to beliefs that fertilizer increases the grass growth. When we did not add fertilizer, the grass at its peak was 16 cm tall. After adding the fertilizer, the grass decreased all the way to 8 cm on the last day of testing. I believe that since the fertilizer solution was extremely concentrated, it caused the grass to die because it did not have enough water, and it was exposed to too many chemicals. Some fertilizers also add salt into the soil that can accumulate to toxic levels over time; high levels of salt in the soil can cause the grass to become dehydrated even when it is watered

Clear cutting forests can be proven to be an unstable way of practising forestry as its long term affects to an environment target the climate, soil conservation, biodiversity and hydrological regimes. Depleting forest resources will be given strict and serious punishment as it affects society as a whole and not

Canada is a country that is well-known for its beautiful land and freshwaters. However, Jackfish Lake in Yellowknife was starting to display abnormal signs of algae growth. Currently, the algae displays a liver-like appearance and is spreading deeper into the lake. The Department of Environment and Natural Resources asks the City of Yellowknife to test this lake and confirm the source of the algae growth. Citizens assume that the Jackfish power

B. I see that there are fewer pill bugs in the grass at patriot park and more in the wooded areas

The Queensland Theatre Company’s rendition of ‘The Wider Earth’ was a highly captivating piece of theatre, which recounted the scientific visionary, Charles Darwin’s voyage on the HMS beagle. Through the extensive manipulation of dramatic languages, in which ritualistic movement, characterisation, tension of relationship, and symbolism were all employed in order to achieve the company’s artistic director, Sam Strong’s aims to have “the cast beautifully transform the various historical and fictional characters into three dimensional human beings.”

Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most
