Natural Environment

There are many civilizations built on rivers. These civilizations experience many advantages, and disadvantages because they live along rivers. Rivers give the natural resource of water. Throughout history many great countries thrived on rivers, Egypt, and Mesopotamia, to name a few. Water from a river can be useful and therefore some civilizations thrived on their rivers, and for other communities the river was their doom.

The Devon River is clean, freshwater, and well dammed up. It is described as being a small, narrow river fringed by pine and birch (pg. 42) On the other hand, the Naguamsett River is described as muddy and

According to Deborah McGregor, the term “environment” encompasses many different aspects of nature. From a contemporary perspective, the environment means the components of the earth such as: land, all layers of the atmosphere, all organic and inorganic material, and interacting natural systems. However, for indigenous populations, “environment” is more than the surrounding physical attributes of nature. The term “world view” emerges from the intense bond between indigenous populations and the environment. As a result environment also encompasses how one views and experiences the world (McGregor, 2015). Unfortunately, McGregor (2004) finds that traditional ecological knowledge surrounding environmental

A river is the same way you can force it to irrigate your crops by creating irrigation canals. Also, they can be used for fishing and ships can trade goods over the water also. When Machiavelli wrote that rivers and men can’t be trusted I also agree with this too, because a man naturally will have a harder time keeping a secret because there is that thrill that only certain people know and they want to be the one to gossip about it. In a different way rivers can’t be trusted because rivers flood unpredictably (unless that river is the Nile) and when it floods it spreads havoc throughout the

This concept is expressed in the inquiry as I will be covering the type of environment inside Princess Margaret Rose Cave and the effect the environment has on the cave including the weather (rain).

Ecosystems is the dynamic complex of plant, animal and micro-organism communities and their non-living environment that work together to form a functional unit and they are constantly changing due to the fluctuating equilibrium from natural stress and human action which has had adversarial impacts on ecosystems. This is evident in Minnamurra rainforest as human induced modifications and environmental stresses had resulted in a vulnerable ecosystem. Furthermore, the removal of factors that contribute to the vulnerability of an ecosystem is important as it affect the functioning of the ecosystem as processes are accelerated, biodiversity is decreased which greatly affects humans. Despite the negative effects caused by humans, they have discovered that ecosystems are susceptible from harm caused by natural environmental factors or human impacts and realised the importance of protecting and managing ecosystems therefore have implemented management strategies that are supposed to prevent further detriment and as a consequence may induce resiliency.

Overall, the more macroinvertebrates in the water, the healthier the stream. pH is a measure of how acidic or basic water is. It is measured on a scale from 0-14. 0 is the most acidic, 14 is the most basic, and 7 is neutral. It is the measure of the relative amount of free hydrogen and hydroxide ions in the water. Acidic water has more hydrogen ions, and basic water has more hydroxide ions. When water’s pH is around neutral (7), that is a suitable and healthy living environment for fish, and indicates a healthy stream. If the water is too acidic or too basic, it can be harmful to the aquatic life. Dissolved oxygen is a measure of how much oxygen is dissolved in the water. As the amount of dissolved oxygen drops below normal levels in water bodies, the water quality is harmed and creatures begin to die off as a result of eutrophication. The higher the level of dissolved oxygen, the healthier the stream. When there is a lot of dissolved oxygen present it makes for a safe environment for fish to live and reproduce. Having all this healthy fish can provide us with food, so overall the more dissolved oxygen, the better. Nitrates are a compound found in fertilizers that is used to help plants grow. It is what is given off as a result of the use of nitrogen in water. The organisms in the soil eat the nitrates and it helps the metabolism and the health of organisms. Plants, such as Algae use nitrates as a source

Running water moves sediment in the processes of erosion and deposition, causing different types of landforms. As you can tell in the picture above, Michigan’s topography plays a huge role on where the faster and slower flowing rivers are located and the transportation of the materials in the water depends on the speed of the rivers. Erosion is the breaking down of those materials by the agent, water. The water can erode the channel laterally and vertically, in the end, making the channel wider and deeper. There are different types of erosion: hydraulic action, corrasion, corrosion, cavitation, and attrition. Hydraulic action (above on the right) takes place at rapids and waterfalls because the force of the water removes rock particles from the bed and banks of the river. A great example of this in Michigan is Canyon Falls on the Sturgeon River. At the waterfall, the water is rushing at a high velocity, especially in the spring, causing rock particles to move downstream, creating a wider and deeper river. Eventually the rivers velocity begins to decrease and particles start to deposit. This could also occur because lack of precipitation or an increase in evaporation. The deposition of materials at different locations of the river that they began changes the shape of the river, and effects Michigan as a whole in the end. The particles can travel all the way to the mouth of the river, in this case, Lake Superior, causing

A) The Indian River Lagoon surprisingly is not a river at all! A river is any body of water that has headwaters and flows into a mouth. The Indian River lagoon has none of the above. When it does flow, it does so in many directions depending on the winds, tides, etc. So what is the Indian River Lagoon classified as? It is considered to be an estuary. That means that the freshwater draining from the land mixes with the ocean’s salt water. Because of all of these factors, there is an abundance of animal and plant life living within its boundaries.

Now that the definition of stream has been defined and a few of its key characteristics discussed, the specific geographical characteristics of Plaster Creek

For example. Waterfalls and potholes are commonly found in the upper course, and are exceedingly rare in the lower course. Meanders and Oxbow lakes are commonly found in the middle course, it is caused by erosion and deposition, these factors causes the river to have a bend during its course. Levees and flood plains are also frequently found in the lower course, there is a larger water volume, therefore floodplains are created to adapt to it’s new features, while features such as meanders will not be affective, as it has a higher chance of flood, and erosion would also change the feature very

Relationships of rocks and their qualities are apparent ubiquitously and are comparable between Clear Creek a nearby Valley Wall. Comparability between Clear Creek and a nearby Illinois River location also display an ever-present relationship of their discharge. Through USGS, the discharge of streams and springs correlate two water types; karst development.

Ecology today can be defined as “the study of the interrelationships between living things and their environment”. It is important to understand that when we say that ecology includes the “environment”, we are talking about everything that is external to an organism, all the biotic and abiotic. Nowadays it also attempts to understand and explain the how and why of the origins and mechanisms of interactions.

I would define nature as the world around us without any type of human involvement. I believe that nature is anything natural to the earth. It is the plants, animals, rivers, forests, birds, weather, etc. It is a gift given to us from god. Most people believe that nature is just centered on the thought of the ocean and forest. Nature to me is the life source for all living creatures it provides us with the four essential things that we need to survive which are food, water, air, and shelter. However, we are so disconnected from nature we do not see the constant damage that is destroying our home.

A photograph of Earth reveals a great deal, but it does not convey the complexity of our environment. Our environment (a term that comes from the French environner, “to surround”) is more than water, land, and air; it is the sum total of our surroundings. It includes all of the biotic factors, or living things, with which we interact. It also includes the abiotic factors, or nonliving things, with which we interact. Our environment includes the continents, oceans, clouds, and ice caps you can see in the photo of Earth from space, as well as the animals, plants, forests, and farms that comprise the landscapes around us. In a more inclusive sense, it also encompasses our built
