this section should be the bulk of your essay; minimum length = 4 detailed paragraphs
Summary vs CritiqueActions
Specifically, address the following questions:
How does the topic of the article affect the Earth as a whole?
How does this article relate to my life?
References (APA format preferred) – Purdue’s OWL (Links to an external site.) website can assist with APA citation formatting
Use the above 6 numbers/headings to organize your essay.
Additional Information:
What is a Critique?
A book report only summarizes the article. A critical essay is you explaining what you think of their data. For a 1000-word essay, the summary should only be about two paragraphs long. The rest of the report should be your thoughts about the topic. Analyze the pros and cons of the article. Is the author presenting good science or just opinion?Is the author a recognized expert?How could the article be improved?
What is Good Science?
The instructions above ask you to evaluate whether the article is ‘good science’. DO NOT just tell me it is ‘good science’. Explain why. Start by asking yourself these questions: Did they try and use the scientific method (Ch. 1)? Did they support the conclusions with facts? Did they provide the facts or a reference to them? If the answer is no to any of those basic questions, then it’s probably not good quality science, and you probably need to find at least 1 more supplemental article to add additional support to your essay.

How does a histogram’s shape help to display a country’s population growth?What shape would a population experiencing rapid growth have?
Population Histograms
How does a histogram’s shape help to display a country’s population growth?What shape would a population experiencing rapid growth have? Slow growth? No growth? Negative growth?
Look at this graph of World Population Growth. Is there any relationship between how industrially developed a country and the population growth of that country? Find examples of more developed countries and less developed countries that support or refute the information on this chart.
What circumstances might result in a high birth rate for a population?A low birth rate?
Factors in Population Growth
The natural increase of a population depends on the number of births and deaths. If the number of
births is greater than the number of deaths at any given point in time there will be natural increase in
the number of people. Typically, the growth rate of a population is given in terms of the birth rate
(number of births per 1000 people per year) and death rate (number of deaths per 1000 people per
year).
1.Write an equation that expresses the growth rate of a population in terms of the birth rate and death rate.
2.What circumstances might result in a high birth rate for a population? A low birth rate?
3.What circumstances might result a high death rate for a population? A low death rate?
4.Look at these charts of Birth and Death Rates. If both birth rates and death rates are declining worldwide, why is the world’s population still increasing? Based on this birth rate and death rate information, what could you say about the world’s growth rate in recent years?
How does this type of environment impact the organisms that live there (esturaries)?
Estuary Salinity Lab
Procedure:
Place a few drops of red food coloring to a clear glass that contains cold water from your refrigerator (less than half full).
In a separate glass of the same type, make a saltwater solution using the same amount of water as you did in step 1. Heat that water in the microwave for1 1/2 minutes or until warm. Be careful not to burn yourself. Dissolve table salt into that warm water (mix a little at a time until it does not dissolve any further.) Then place a few drops of yellow food coloring to that solution. Mix well.
Now, slowly pour the red water solution (freshwater) into the saltwater solution (yellow solution). The slower you pour the red into the yellow the better your results will be. Hint: If you pour it so that the red solution moves down the side of the yellow container, slowly, you will recieve nice reults.
Do not stir or mix this combined solution. You should see a seperation of the two solutions, even though they are in the same container.
In a word or google document, describe what you observed as you mixed these solutions and then continue to monitor the solution recording what you see happening each minute for 10 minutes. Make a data table of these observations.
Take pictures of the mixture immediately after mixing and then after 10 minutes. Place a copy of these pictures in your lab writeup and label the pictures.
Answer the following analysis questions.
Which solution was above the other?
Why did the solutions seperate and not mix?
How does this lab help to represent what happens in estuaries?
How does this type of environment impact the organisms that live there (esturaries)?
What types of stress does this place on the organisms?
How might historical events or the quality of life during different historical periods have influenced population growth?
Population Explosion
1. Look at the U.S. Census Bureau’s World Population Clock gives an up to the second estimate of the world population. By how much does the population grow in 1 minute? How many people is that per second? Per week?
2. Using the U.S. Census Bureau’s State and County Quick Facts, find the most recent population estimates for Georgia and Forsyth County. How does your county population compare to the number of people the world population grows by each week? Are you surprised by the results?
3. Look at this graph of Historical Estimates of World Population. In what year did the world
population start to suddenly increase? What do you think might be the cause for this?
4. How might historical events or the quality of life during different historical periods have influenced population growth? Check the World HyperHistory site to see what may have influenced population growth during different periods in time. Focus on major historical events such as different Disease events and World Wars.
5. According to this Population Growth Rate Map, in what areas of the world has the population been growing most rapidly? Why do you think this is?
How does the current motion of HNLC on Oahu compare to the direction of Pacific Plate motion relative to the Hawaiian hotspot over the past 42 million years?
Lab 2 Tectonic Plates
Hotspots and Plate Motions Activity 2.4 Name’ Learning GOAL You will learn how the volcanic trail left on a plate by a mantle hotspot can be interpreted to tell us where and how fast the plates are moving relative to Earth’s deep mantle. As a lithospheric plate moves over a hotspot in the upper mantle below the plate, a volcano develops directly above the hotspot. As the plate continues to move, the volcano drifts away from the hotspot and eventually becomes dormant. Meanwhile, a new volcano develops over the hotspot next to the older volcano. The result is a trail of volcanoes with one end of the line located over the hotspot and quite active, and the other end distant and inactive. In between is a succession of volcanoes that are progressively older with distance from the hotspot. geFigure 2.13 shows the distribution of the Hawaiian Islands Chain and Emperor Seamount Chain. The numbers indicate the aver-age age of the volcano in millions of years (Myr), obtained from isotopic dating of the basaltic igneous rock of which each island is composed.
Course/Section:
Date:
1. If both the Emperor and Hawaiian Islands Chains developed as a result of the same mantle hotspot, what is a possible reason that the hotspot trail changes direction at —42 Myr?
2. What was the rate of Pacific Plate motion relative to the Hawaiian hotspot as it was developing the 2,300 km-long Emperor Seamount Chain from 65 Myr to 42 Myr? Express the rate in millimeters per year (mm/yr). In what direction was the plate moving (north-northwest or south-southeast) relative to the hotspot during that time interval?
3. What was the rate of Pacific Plate motion relative to the Hawaiian hotspot from 5.1 to 0.8 Myr, expressed in mm/year?
4. Using Lo’ihi Seamount as the current location of the Hawaiian hotspot, what was the rate of Pacific Plate motion relative to the Hawaiian hotspot from 0.8 Myr to today, expressed in mm/yr?
5. Go to the JPL-NASA GNSS Time Series website at https://sideshow.jp1nasa.gov/Post/series.html. The map locates each GPS station with a green dot and a yellow line that extends outward in the direction that the GPS station is moving relative to the NNR reference frame. GPS station HNLC is located on Oahu.
How does the current motion of HNLC on Oahu compare to the direction of Pacific Plate motion relative to the Hawaiian hotspot over the past 42 million years?
GPS station HNLC on Oahu has the following component velocities relative to the NNR reference frame as of March 5, 2019: moving north at 34.607 ± 0.038 mm/yr and moving west at 62.814 ± 0.041 mm/year. Use the Pythagorean Theorem to find the current speed of the Pacific Plate at Oahu relative to the NNR reference frame. Show your work.
6. REFLECT & DISCUSS Based on all of your previous work, explain how the direction and rate of Pacific Plate movement changed over the past —70 million years.
What do you think will be the composition of most of the sedimentary grains deposited in Lake McClure from Yosemite Valley?
Sedimentary Processes,Rocks,and Enviornments
Use your observations to make predictions. The Merced River flows from Yosemite Valley at an elevation of —1,200 m above sea level in central Yosemite Valley to an elevation of —250 m where the river enters Lake McClure, a reservoir in the San Joaquin Valley west of Yosemite Valley. The actual distance the river travels along its channel from Yosemite to the upper end of Lake McClure is more than 65 km. You can examine the Merced River course between latitude 37.72N, longitude 119.63°W (central Yosemite Valley) and 37.602N, 120.100°W (inlet to Lake McClure on the Merced River) using Google Earth.
What sedimentary grain sizes are likely to be deposited in Lake McClure from the erosion of Yosemite Valley?
What do you think will be the composition of most of the sedimentary grains deposited in Lake McClure from Yosemite Valley?
11/ REFLECT & DISCUSS Based on your work, write a brief description of how the elastic sediment from Yosemite Valley might change as it travels downstream to Lake McClure. Then describe how you could use these insights to interpret elastic rocks in general.
