Natural Selection can occur within a population even in the absence of overpopulation, but it needs to be a potential for the environment to exert selective pressure on the population and favour some adaptations over others.
What is overpopulation ?When the human population increases above the ecological environment's bearing capability, it is said to be overpopulated. In an overpopulated area, there may be more people than there are resources that are necessary for their existence, such as transportation, water, shelter, food, or social amenities. This frequently causes the environment to deteriorate, the quality of life to decline, or even the people to disintegrate.An estimated 81 million people join the world's population per year. The terrible consequences and issues of overpopulation are most evident in areas with the highest population density. Populations will constantly grow as a result of immigration, the drop in mortality rates, advancements in medicine, and higher birth rates, eventually leading to overpopulation.

2. If you send your soil out for a test and find out that it contains 75% silt and 25% clay, what kind of soil do you have
Answer:
if you send your soil out for a test and find out that it contains 75% silt and 25% clay, what kind of soil do you have?
Pure loamExplanation:
Pure loam is considered to be the best kind of soil for a farm or garden and is often defined as a soil with roughly equal proportions of sand, silt, and clay.
The best type of soil for growing plants is called loam soil. It is essentially a mix of soil that often contains equal amounts of clay, silt, and sand and offers the advantages of each with few drawbacks.
What are the features of loam soil?Sand, silt, and clay are present in loam soils in amounts that strike a balance between their stickiness and non-stickiness, making them moldable but not sticky.
Sand, clay, and silt particles combine to form loamy soils, which are thought to be the most fertile type of soil.
Sand lessens compaction and enhances drainage, while clay and silt particles enhance moisture retention. Neither do loamy soils become waterlogged in the winter, nor do they dry out in the summer.
Therefore, Pure loam, which is sometimes described as soil with nearly equal amounts of sand, silt, and clay, is thought to be the greatest sort of soil for a farm or garden.

In this project, you will compare the descriptions of a national park over the last hundred years. Choose a national park to complete the following:
1) Locate a primary source describing the geography and environment of the park. This source should have been written either before, or close to, the time that the park was founded.
A primary source is an original document or artifact that comes from the period of time being studied. Someone from that time period actually wrote, created, or used the object being studied.
Examples of primary sources are diaries, letters, oral histories, and eyewitness accounts.
When searching for a source, consider looking for something written by John Muir, Lewis and Clark, or Theodore Roosevelt. Each of these men wrote descriptions of many of the parks that are protected today.
2) Paraphrase the author’s description in the comparison chart. Be sure to record key characteristics of the geography; you will want specific details for your writing.
To paraphrase information:
Reword the passage from source material in your own words.
Aim for a shorter and slightly condensed version of the original material.
Attribute material to the original source.
3) Locate a secondary source describing the geography and environment of the park today.
Secondary sources are documents written after the event occurred. They provide a secondhand account of the event or topic. Secondary sources often contain more analysis, or even conclusions, regarding the events or topics discussed.
Examples of secondary sources are newspaper and journal articles, academic textbooks, encyclopedias, reference books, and other nonfiction books and websites.
4) Paraphrase the author’s description in the comparison chart. Record specific details and pay close attention to similarities and differences you notice between this source and your previous one.
Then, using your completed comparison chart, create a multimedia comparison of the similarities and differences between the two sources. Your comparison should have at least three sections or paragraphs and can be in the format of a wiki, a Web site, or an interactive poster on the national park.
In the first paragraph or section, discuss the similarities between the descriptions in your sources about the park. Your first paragraph should have at least one properly cited quote and be 70 words long.
In a new paragraph or section, contrast the descriptions of the park in the two sources, explaining what has changed since the park has opened. Your paragraph should have at least one properly cited quote and be 70 words long. Include a properly cited picture of the park to add to your information.
In the final section, analyze the changes that occurred in the park and what caused them. Your paragraph should be well-developed, with complete and complex sentences, and at least 70 words long. Add either a source or a relevant picture to your project that enhances the quality of your presentation. Remember to properly cite your sources.
At the end of your project, create a bibliography page that properly follows the APA Style Citation Guide for citations.

Gondwana moved northward during the Carboniferous, and periods of sea level rise/fall due to melting/advancing glaciers caused unique cyclic rock sequences of nonmarine and marine deposition. These are called ____________________.
Gondwana moved northward during the Carboniferous, and periods of sea level rise/fall due to melting/advancing glaciers caused unique cyclic rock sequences of nonmarine and marine deposition. These are called cyclothems.
In geology, cyclothems are alternating stratigraphic sequences of marine and non-marine sediments, sometimes embedded with coal seams. Historically, the term was defined by European coal geologists working with coal pans formed during the Carboniferous and early Permian periods.
The deposit sequence has been exhaustively explored by petroleum geologists using geophysical profiles of continents and ocean basins. A common theory of basin-scale sedimentation is formalized under the name sequence stratigraphy.
Since the Carboniferous was a widespread ice age in the Southern Hemisphere, it is likely that several cyclothems formed as a result of oceanic regressions associated with the growth and collapse of ice sheets, respectively. A more common interpretation of the sequence gives rise to Milankovitch cycles.

The three zones to be to be classified of a river system are as following:-
Zone of sediment production (Streams in the mountain)Zone of sediment transportation (River in between the mountain and shore)Zone of sediment deposition (Streams that end at the shore)Explanation:-Production of sediment will fall under initial zones. Sediment may be created in a variety of ways, such as when igneous and metamorphic rocks are exposed to wind and water and weather. decay of the wildlife and plants. However, the majority of sediments are produced when rocks are broken down by streams, rivers, and other moving bodies of water. Rocks may also be weathered extensively by wind. sediment formed by the weathering of rocks is found in the first zone.
The second zone will cover sediment transport. The slope (which may be caused by any type of landform) allows the produced sediment to flow and travel downhill, according to the diagram.
Under the third zone, sediment deposition occurs. Because the flow of the streams ceases at the bottom, all carried silt will be deposited there.

imagine yourself as a farmer owning land which is infertile.
How would uh convert it into a fertile farmland
Answer:
Water harvesting: Since the soil was eroded, they first set up water harvesting structures, such as swales, trenches, percolation tanks. These systems increased the efficiency of water use, recharged four existing borewells (which were not effective) and ensured a regular supply without taking from the reservoir.
Sapling plantation: Water harvesting is incomplete without planting. Saplings from government and private nurseries were used in the first plantation cycles. A nursery was set up to host young trees and plants which were later planted at Polam. The goal was to revive soils and life by planting diverse species.
Fencing: In an arid region, fires are common. To avoid damage, live fences were raised around the boundaries, and windbreaks such as huge teak trees were planted to brave the South wind blowing from the reservoir. Fruit trees have now fully reforested another 2 hectares acre of the farm. The fruit forest has become a new habitat for insects, animals and birds.
Regenerate through biodiversity: In the rest of the land, trees and plants have been scattered between local species, which adapt to the dry land climate, and tropical species. Although some died, diversification ensures that there is regeneration of life.
Animals: Animals playing a key role in regeneration. Chickens, bullocks and cows were integrated in the everyday activities. The chickens provide eggs and their excreta enriched compost. Bullocks are used for ploughing and sowing.
Local crops: Local crops such as millets, pigeon peas, green grams are also grown. Seasonal vegetables from the garden such as brinjals, curry leaves, cluster beans, rosella plants are used for daily consumption and will also be served to the 600 participants at the IPC.

Southern California is famous for its wildfires, which are often exacerbated by the Santa Ana winds blowing through the canyons. What mass wasting event will later devastate the same fire-affected areas
The mass wasting event which will later devastate the same fire-affected areas is called Mudflows
Why do mudflows happen?
Mudflows occur when significant amounts of water collect to quickly erode soil on a steep slope. Mudslides happen when a lot of water builds up and quickly erodes the soil on a steep slope. As a result of heavy rain, for example, water seeps into the soil and separates the soil grains.
A muddy substance's starting point for flow is influenced by its particle size, water content, and topographical slope. In contrast to coarse sediment or a debris flow, shallower flows can transport fine-grained particles like mud or sand. A mud flow can start more easily when there is more water present (more precipitation or overland flow).
Coarser material may be swept up by a mud flow after it forms. Finer sediment and water that pools up behind the flowing front of the coarse-grained mudflow push the coarser silt that was taken up by the flow and often forms the front of a mudflow surge.
