Answer:
A primary source is anything that gives you direct evidence about the people, events, or phenomena that you are researching. Primary sources will usually be the main objects of your analysis. If you are researching the past, you cannot directly access it yourself, so you need primary sources that were produced at the time by participants or witnesses (e.g. letters, photographs, newspapers).
A secondary source is anything that describes, interprets, evaluates, or analyzes information from primary sources. Common examples include: 1. Books, articles and documentaries that synthesize information on a topic 2. Synopses and descriptions of artistic works 3. Encyclopedias and textbooks that summarize information and ideas 4. Reviews and essays that evaluate or interpret something When you cite a secondary source, it’s usually not to analyze it directly.
Examples of sources that can be primary or secondary:
A secondary source can become a primary source depending on your research question. If the person, context, or technique that produced the source is the main focus of your research, it becomes a primary source.
To determine if something can be used as a primary or secondary source in your research, there are some simple questions you can ask yourself: 1. Does this source come from someone directly involved in the events I’m studying (primary) or from another researcher (secondary)? 2. Am I interested in analyzing the source itself (primary) or only using it for background information (secondary)?
Most research uses both primary and secondary sources. They complement each other to help you build a convincing argument. Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research.
The examples of sources of information can be mentioned as below,
Primary sources of information – Journal; Thesis, primary survey.
Secondary sources of information – Encyclopedias; articles; research materials.
What is the significance of primary and secondary sources?Primary sources of information are sources that contain firsthand information about any subject or topic of research. Secondary sources, on the other hand, include information collected from previously available sources in the public domain.
Journals, theses, and surveys are some examples of primary sources of information; whereas, encyclopedias, articles, and research materials are some examples of secondary sources of information.
Therefore, the significance regarding primary and secondary sources has been aforementioned.

Given directed line segment CD, if point E divides CD three-fourths of the way
from C to D. find the coordinates of E. Round to the nearest tenth.
Answer:
E(-2, -1.5)
Explanation:
From the diagram attached, the coordinates of point C and D are at C(1, 6) and D(-3,-4)
If a line segment AB with coordinates at [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is divided by a point O(x, y) in the ratio n:m, the coordinates of point O is given by the formula:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]
C(1, 6) and D(-3,-4) are divided three fourths (in ratio 3:1) by point E. Let us assume E is at (x,y), hence the coordinate of point L is given as:
[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1=\frac{3}{4}(-3-1)+1=\frac{3}{4}(-4)+1=-2 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1=\frac{3}{4}(-4-6)+6=\frac{3}{4} (-10)+6=-1.5[/tex]
Point E is at (-2, -1.5)

Which of the following is not one of the three types of physical processes that can cause weathering? A. biological B. cultural C. chemical D. physical
Answer:
Cultural
Explanation:
The physical properties that lead to weathering are the heat, the temperature, the pressure, frost, the root action, and the burrowing animal. Thus this process leads to an increase in the surface of the exposed area. and leads to a large number of disintegration.
Hence culture is not a type of physical weathering.As all the physical process includes physical and chemical activities it also includes the biological activities of the plants and animals, including man. The physical process leads to the disintegration that is the wear and tear of rocks.
Hence the above-mentioned process is associated with physical weathering except culture.

Answer: Below is an overview of some elemental information related to limnology and lake management that are important to know in understanding lakes and the big picture of lake management. For more detailed information please visit the NALMS Bookstore, which has numerous publications on general limnology and lake-related topics.
Basin Types
Events that occurred on or beneath the Earth’s surface thousands of years ago formed many of our lakes. As a result, lakes are usually concentrated into areas that have a large number of waterbodies. Most lakes can be found in the Northern Hemisphere, where large areas were covered by huge ice formations. On a scale of human life spans, lakes seem to be permanent features of our landscape, but they are really only geologically temporary. They are created, mature (fill-in) and eventually disappear.
The origins of the lake basins and their characteristics ultimately reflect the physical, chemical and biological events taking place within the area surrounding them. These events play an important role in how the lake responds to surrounding activities.
Glacial Lakes: By far the most important agents in the formation of lakes are the catastrophic effects of glacial ice movements that occurred 10,000 to 12,000 years ago. Gigantic sheets of ice and snow are created in climates where snow falls but does not melt. The glaciers covered an area from the Atlantic Ocean to the Rocky Mountains in ice that was more than a mile high. Although these glaciers did eventually melt, ten percent of the earth is presently covered with glaciers. Some of these glaciers can still be seen in the mountainous areas of the United States and Canada.
As a glacier moves back and forth across the land, scraping off the tops of hills and bluffs and taking rocks with it, lakes are formed. The material picked up by the glacier is later dropped off at other sites. This back and forth and stop and go movement of the glaciers permanently alters the landscape. This movement creates several important landforms. When the glacier stops, it leaves behind piles of rocks and materials that it carried over time, called moraines. These dam up rivers and smaller streams to form lakes. Sometimes, huge blocks of ice are broken off and covered by sand and gravel. When the ice melts, the sand and gravel cave in, leaving a large hole behind. These kettles may form large marshes or lakes. As the large mass of ice melts, rivers form beneath the glaciers.
Solution Lakes: Lakes can form when underground deposits of soluble rocks are dissolved by water running through the area, making a depression in the ground. Rock formations made of sodium chloride (salt), or calcium carbonate (limestone), are most likely to be dissolved by acidic waters. Once the groundwater has dissolved the rocks below the surface, the top of the land caves in, usually forming a round-shaped lake, called a solution lake. Typically, the depressions are deep enough to extend below the groundwater table and are permanently filled with water. Solution lakes are common in Michigan, Indiana, Kentucky and particularly in Florida.
Oxbow Lakes: The flow of water from rivers has a great deal of energy and erosive strength that may create lake basins. As a river winds over the earth’s surface, a greater amount of erosion occurs on the outer river bend, where the flow of water is the fastest. Materials carried by the river are deposited on the inner portion of the bend, where currents are reduced. As time passes, erosion continues and more materials are left off until the U-shaped meander of the river closes in. The main course of the river cuts a new channel to the inner end of the meander. Oxbow lakes are usually shaped like the letter C.
Man-made or Animal-made Lakes: Many small lakes in North America have been formed by the activities of the American beaver. Sticks, aquatic plants and mud are used to build dams across small streams to form an impoundment of the water. These ponds are usually very shallow and are rich in nutrients and plant life. Humans have constructed artificial lakes (reservoirs) to supply drinking water to the public, to provide power, to aid in navigation, to provide flood control and for recreational purposes. These reservoirs are usually well engineered by humans to hold back a certain quantity of water with the use of dams.
Volcanic Lakes: Sometimes, disastrous events associated with volcanic activity form lake basins. The formation of volcanic lakes can occur in different ways. As volcanic material, including magma, is discharged out of the volcano, empty depressions or cavities are formed within the volcano. Some of these depressions cannot drain and become sealed holes on top of the volcano. Rainfall and runoff eventually fill the depression with water and a new
Explanation:
The edge of a continent is found atthe boundary between low-densitycontinental rocks and higher-density oceanic rocks-The deepest parts of the oceans occur in elongate narrow trenches that areassociated withsubduction zones-Why do ocean water depths increase away from the midocean ridges?The accumulation of sediments over time adds weight to the sea floor. Older oceanic crust is denser and thus sits lower on the asthenosphere.-According to plate tectonic theory, the initiation of a rift zone is caused by the rise of hot mantle material toward the Earth's surface-Convection cells in the mantle form when hot mantle material rises, moves laterally, and then sinks when it becomes cold.Approximately 220 million years ago, the continents were joined together intoone supercontinent known as Pangaea. This super-continent was surroundedby an ocean named PanthalassaWhich of the following was the only process to occur during the last 65 millionyears?India rammed into Asia.The lateral spreading of the plates away from the elevated midoceanridge is driven in part bygravitational pullWhat led James Hutton to propose the the Earth must be extremely old?Henoted that natural processes, such as erosion, were very slow.

Apply: An archaeologist finds a golden figurine. How could she determine if the figurine is solid gold without cutting it?
Answer: By weighing it
Explanation:
The density of gold is known to be 19.3 g/cc and this was derived by dividing a particular mass of gold by its volume. As the density is already know, the archaeologist can then estimate the size of the figurine. Using the estimated size and the density, the archaeologist should be able to come up with a theoretical weight.
The archaeologist should then weigh the figurine. If the figurine's mass is quite different from the theoretical mass then it probable isn't solid gold.
