Rivers are frequently used as the subject of geographical investigations. They are dynamic systems, which means they are continually changing, which explains why.
What do you mean by Rivers?A river is a body of water that flows downward due to gravity and has the appearance of a ribbon. A stream, creek, or brook is a flowing body of water that is smaller than a river.
A river may be wide and deep, or it may just be shallow enough to be crossed by wading.
Only during the rainy season, when the water table is higher than the riverbed, do periodic rivers receive their water supply from underground.
Because they are a valuable natural resource, rivers are crucial to a nation's economy.
By transporting mineral-rich silt, they not only supply water for irrigation operations but also ensure soil fertility.
They are helpful for transportation and navigation, and they also produce hydroelectricity.

Correct answer will be, sediment, metamorphic rock, sedimentary rock, weathering and erosion. This is correct on Edge 2020.
The rock cycle depicts the evolution of the three main types of rocks over the span of geologic time: sedimentary, metamorphic, and igneous. A rock changes when it is forced outside of its stable environment. For example, when exposed to air or subducted beneath a continent, an igneous rock like basalt may crumble and evaporate. The driving forces of the rock cycle, plate tectonics, and the water cycle prevent rocks from remaining in an equilibrium state; instead, they change as they interact with new surroundings. The rock cycle illustrates how the three different types of rocks are connected to one another and how processes shift over time from one type to another.

this image of the alien planet shows dark material with a few craters protruding into heavily cratered, lighter-colored terrain. some of the dark material even fills in the craters of the light-colored terrain. what type of mineral is the dark material probably made of?
The abundant dark-coloured minerals include olivine, pyroxene, amphibole, biotite, garnet, tourmaline, iron oxides, sulfides, and metals.
Amphiboles often have a dark hue and contain the elements calcium, iron, and aluminium. The most prevalent amphibole is hornblende, which ranges in hue from dark green to black. In both igneous and metamorphic rocks, amphiboles are typical. Deep-water rocks, such as those found in the ocean or large lakes, have less oxidised iron minerals and are more frequently black or grey in colour. The colour of the rocks may be more greenish or brown if they were dumped in shallow water. Rhyolite, andesite, and basalt are often found extrusive rocks. Basalt is a typical solid, black, massive rock with a low quartz content and a high concentration of calcium and iron-magnesium-bearing minerals.

the weather on four different summer days is described below. on which day would you expect the greatest temperature range? which day would have the smallest range in temperature?
The day with the widest temperature variation would be the one with both daytime and nighttime clear skies.
The day with the narrowest temperature range would be the one with cloudy skies both throughout the day and at night. In order to prevent the temperature from increasing too much, clouds reflect and block some of the incoming sunlight. There isn't much of a variation in temperature between day and night because clouds prevent some heat from escaping the atmosphere throughout the night. Contrarily, on a sunny summer day, the Earth's surface receives a lot of sunlight and warms up. If the sky is clear through the night, this cools down.

climate unit test 2 of 152 of 15 items question use this sentence: john lives on a part of earth where the angle of the sun's rays are very high, and the latitude is low. which temperatures does john experience quite often?
Answer:
John is likely to experience mostly high temperatures.
Explanation:
If John lives on a part of Earth where the angle of the Sun's rays is very high and the latitude is low, he is likely to experience high temperatures quite often. The angle of the Sun's rays is a measure of the inclination of the Sun's rays with respect to the Earth's surface, and it is determined by the latitude and the time of year. At low latitudes, the Sun's rays are more direct and perpendicular to the Earth's surface, and they provide more heat and light to the region.
The latitude of a location is a measure of its distance from the equator, and it is used to determine the amount of heat and light that a location receives from the Sun. Locations at low latitudes are closer to the equator, and they experience more direct sunlight and higher temperatures throughout the year. In contrast, locations at high latitudes are further from the equator, and they experience more indirect sunlight and lower temperatures.
Overall, if John lives on a part of Earth where the angle of the Sun's rays is very high and the latitude is low, he is likely to experience high temperatures quite often, as the Sun's rays provide a large amount of heat and light to the region. The exact temperature that John experiences will depend on the specific location and the time of year, but in general, he can expect to experience warm to hot weather throughout the year.

Based on what you have learned about global trends in terrestrial ecosystems, what is currently the largest threat to the wet tropical forests in central america?.
Currently the largest threat to the wet tropical forests in central America is habitat destruction, such as the clearing of forests for coffee plantations.
Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is Invasive Species.
The process by which a natural ecosystem can no longer support its native species is known as habitat destruction. Decreased biodiversity and species overflow result from the relocation or passing of the animals that once involved the region. The deficiency of biodiversity is for the most part brought about by living space corruption.
An imported organic entity that overpopulates and harms its new environment is alluded to as an invasive species. Despite the fact that most of imported species are impartial or supportive to different species, intrusive species adversely affect territories and bioregions, hurting their biology, the climate, as well as their economy.
The most successive strategies for obtrusive plants, creatures, microorganisms, and different species to spread to new biological systems are believed to be human exercises like those engaged with worldwide exchange and the pet exchange.

Answer:
Ice wedging
Explanation:
Water seeps into cracks in the rocks, and, as the temperature drops below freezing, the water expands as ice in the cracks. The expansion exerts tremendous pressure on the surrounding rock and acts like a wedge, making cracks wider. After repeated freezing and thawing of water, the rock breaks apart.
