What are the 7 indicators of water quality?
Dissolved oxygen, pH, temperature, salinity, and nutrients are among them (nitrogen and phosphorus). They also include toxicant levels such as insecticides, herbicides, and metals. Physicochemical indicators provide data on what is affecting the system.
Water quality is determined by several factors, including dissolved oxygen concentration, bacteria levels, salt (or salinity), and the amount of material suspended in the water (turbidity). To determine water quality, some bodies of water measure the concentration of microscopic algae as well as the quantities of pesticides, herbicides, heavy metals, and other contaminants.
There are three types of water quality parameters physical, chemical, and biological.
Certain contaminants in our water can cause health problems such as gastrointestinal illness, reproductive issues, and neurological disorders. Infants, young children, pregnant women, the elderly, and people with compromised immune systems may be particularly vulnerable to illness.

Continental glaciers are usually thicker in their center. Looking at this map of crustal rebound in Canada, there were two centers of ice sheet flow. Which covered Canada in the Pleistocene.
An ice sheet is a mass of glacial ice more than 50,000 square kilometers (19,000 square miles). About 99% of the freshwater on Earth is found in ice sheets, which are also known as continental glaciers. Ice sheets transform into ice shelves as they reach the shore and cross the ocean. Only Antarctica and Greenland are the most polar places with continental glaciers. Large portions of Canada, Europe, and Asia were once covered by continental glaciers, and these glaciers are to blame for many of the regions' distinctive geographical features. On land, glaciers develop. They are composed of snow that has fallen and has been compacted over many centuries into ice. Due to the influence of gravity, they progressively descend. The polar regions, including Greenland, the Canadian Arctic, and Antarctica, are home to the majority of the world's glaciers. Compare oceanity to an ice sheet that covers a sizable portion of a continent. An ice sheet is another name for a continental glacier. The reason why these ice sheets are called glaciers is because they cover continental land masses.

two students are talking about what causes the tides. student a says that the tide comes in and goes out based on differences in the height of the sea level. student b says that the changing tides are caused by earth rotating into and out of the tidal bulges. which explanation is more technically correct? why?
Technically, student A is more accurate. The difference in sea level height, according to student A, is what causes the tide, whereas the earth's rotation in and out of the tidal bulges, according to student B, is what causes the shifting tides.
The daily rise and fall of the tide is brought on by the gravitational pull of the sun and moon, according to the definition of the general cause of tides. The varying heights of the water during the day correspond to the rising and falling of the tides. The varying distance between the earth and the moon is what causes the daily variations in tide heights.
In order to study tides and the different phenomena that affect tides, such as hurricanes and winter storms, scientists monitor the height of the water level. They result from the earth's gravitational pull from the moon and, to a lesser extent, the sun. A shore experiences a high tide when the wave's highest point, or the crest, reaches it. A coast suffers a low tide when the trough, or lowest point, approaches it.

Explanation:
The largest river in the world is the Nile River! Spanning across 4.132 miles, it begins in the rivers that flow into Lake Victoria (located in modern-day Uganda, Tanzania, and Kenya) and empties into the Mediterranean Sea more than 6,600 kilometers to the north, making it one of the longest river in the world.
The Nile River flows from south to north through eastern Africa. From its headwaters in Ethiopia and the central African highlands to the downstream regional superpower Egypt, the Nile flows through 10 nations;, Burundi, Tanzania, Rwanda, the Democratic Republic of the Congo, Kenya, Uganda, Sudan, Ethiopia, and South Sudan. But by a quirk of British colonial history, only Egypt and its neighbor Sudan have any rights to its water.
The Nile River flows north from its source. This river flows over 4,100 miles before it reaches the Mediterranean Sea, the location of the Nile Delta. It also has three main tributaries which are the White Nile, the Blue Nile, and the Atbara.
The Nile Rivers composes of 4 main dams;
Aswan High Dam, Aswan High Dam
Sudan, the Sennar Dam on the Blue Nile River.
Grand Ethiopian Renaissance Dam in Ethiopia.
"The water quality of mid-stream Nile water is still, at a clean level on an average, due to the dilution effect and the degradation of the discharged pollutants." (Abdel-Satar, 2005). But that was in 2005, a few environmental challenges have been introduced since then and some are ones that need to be dealt with. Egypt is also believed to face a nationwide fresh water shortage by 2025. Already around seven percent of Egyptians lack access to clean drinking water and over eight million go without proper sanitation. The waters are mainly being polluted by municipal and industrial waste, with many recorded incidents of leakage of wastewater, the dumping of dead animal carcasses, and the release of chemical and hazardous industrial waste into the Nile River.

How do orcas eat without swallowing water?
The orcas expand their mouths almost 90 degrees and suck down some seawater. Then, when their neck pouch deflates, they force the saltwater out of the mouth while capturing krill and microscopic fish in their baleen.
The whale seems like a swollen tadpole as water flows into its mouth and stretches the pouch in its neck. The neck pouch deflates after roughly a minute when the majority of the water exits the whale's mouth and is discharged into the ocean.
When feeding, an adult blue whale may ingest up to 10,000 gallons of fresh water at once. But the whale forces the majority of the water out of her mouth and filters the food through her baleen, so she doesn't consume all of it.

what type of weathering occurs when joints within rocks are aligned so that layers of rock break off and new layers are exposed?
When joints within rocks are aligned, a type of weathering known as mechanical weathering takes place whereby layers of rock break off and new layers are revealed.
Due to the fact that nature is constantly active, even if this activity occurs more slowly than human senses can perceive, mechanical weathering is a physical process that occurs continuously in the environment. As an illustration, we can feel temperature changes from day to night, yet we cannot see a rock swell and shrink as a result of these temperature changes. The rock does, however, experience this imperceptible movement, which weakens it and finally leads to its fracture and breakdown. This is just one instance of mechanical weathering. Let's examine each of the several mechanical weathering processes in more detail.
We've been talking about how changing temperatures effect rocks. Minerals have a propensity to expand and contract in response to temperature, a phenomenon known as thermal expansion.

What does geological structure mean?
The strong tectonic forces that occur within the earth are typically what cause geologic structures. These forces result in deep faults, rock folding and breaking, and mountain formation.
The study of the three-dimensional distribution of rock units in relation to their deformational histories is known as structural geology. The main objective of structural geology is to understand the stress field that produced the observed strain and geometries by using measurements of the current rock geometries to learn about the history of deformation (strain) in the rocks.
A common objective is to comprehend the structural evolution of a specific region with respect to regionally widespread patterns of rock deformation (for example, mountain building, rifting) caused by plate tectonics. This understanding of the dynamics of the stress field can be linked to significant events in the geologic past.
