Small, branching channels that carry water away from the main river channel and carry it over the surface of the delta are known as:
Small, branching channels that carry water away from the main river channel and distribute it over the surface of the delta are known as distributaries.
Distributaries are common features of river deltas, which are formed at the mouth of a river where it empties into an ocean or sea. When a river reaches the end of its journey and enters the ocean or sea, it slows down and loses energy, causing sediment to settle out of the water and accumulate.
Over time, this sediment builds up and forms the delta. The distributaries of the delta help to distribute the water and sediment across the surface of the delta, creating a complex network of channels and islands.
The branching channels of the delta can change over time as the river's flow and sediment load change, and as sea level and other environmental factors shift. Some distributaries may dry up over time, while others may become more dominant as the river's main channel shifts course.
In summary, distributaries are small, branching channels that carry water away from the main river channel and distribute it over the surface of a delta. They are important features of river deltas and help to shape the landscape of these dynamic environments.

The light emitted by Earth's surface will encounter radiation and some resistance as it travels through the atmosphere, due to the various gases and particles present in the atmosphere.
Some of the longer wavelengths of infrared radiation, such as those emitted by the surface at night, are more likely to be absorbed and re-radiated by greenhouse gases in the atmosphere, such as carbon dioxide and water vapour.
This is known as the greenhouse effect, and it contributes to the Earth's temperature remaining within a range suitable for life.

If a long-lasting glacier melted and a stream replaced the ice in the valley floor, the valley shape would eventually be described as a U-shaped valley.
When a glacier carves its way through a mountain, it leaves behind a U-shaped valley with steep sides and a flat bottom. As the glacier moves down the valley, it picks up rocks and other debris, which act as a sort of abrasive to carve the valley floor into a smooth, flat surface. When the glacier melts, the water that flows down the valley erodes the floor further, creating a deeper and wider valley. Over time, the stream will continue to carve out the valley floor, creating a V-shaped valley.
However, the steep sides of the U-shaped valley will remain intact, giving the valley a unique and recognizable shape. The valley will likely also contain evidence of the glacier's presence, such as moraines (debris left behind by the glacier) and striations (scratches left in the rock by the glacier's movement).

The valley shape would likely be a V-shaped valley, which is a common feature created by streams eroding through the landscape over time. The stream would have carved out the valley floor, creating a channel and exposing the underlying rock and soil.
The sides of the valley would also likely be steep and sloping, with the stream continuing to erode the rock and soil over time. Overall, the valley would be a result of the interplay between the forces of erosion and the underlying geology of the landscape.After the long-lasting glacier melted and was replaced by a stream, the valley floor would undergo significant changes due to the erosive power of the flowing water. Over many years, the valley shape would likely change from the classic U-shape that is typical of valleys carved by glaciers, to a V-shape that is more characteristic of valleys carved by rivers.This is because glaciers carve valleys by grinding away the rock underneath, creating a wide U-shaped valley with steep sides and a flat floor. In contrast, streams and rivers carve V-shaped valleys by eroding the rock and sediment on the valley floor and sides over time.So, after many years of erosion by the stream, the valley shape would be best described as a V -shaped valley. However, it's important to note that the exact shape of the valley would depend on factors such as the volume and speed of the water flowing through the valley, the type of rock that makes up the valley walls and floor, and the climate and weather conditions in the area.

in a meandering river, where will we find erosion and deposition respectively?
In a meandering river, erosion typically occurs on the outer banks of the river bend, where the water is flowing faster and has more energy to pick up and carry sediment.
Deposition, on the other hand, typically occurs on the inner banks of the river bend, where the water is flowing slower and has less energy to carry sediment, causing it to be deposited on the river bed. This deposition can eventually lead to the formation of point bars, which are elevated areas of sediment on the inside of a river bend. In a meandering river, you will find erosion on the outer banks and deposition on the inner banks. Erosion occurs on the outer banks due to the faster water flow, while deposition occurs on the inner banks as the water slows down and sediment accumulates.

To calculate the wavenumber for light with a wavelength of 7.20 μm, we can use this equation and convert the wavelength to units of centimeters:
λ = 7.20 μm = 7.20 x 10^-4 cm
ν = 1/λ = 1/(7.20 x 10^-4 cm) = 1388.9 cm^-1
As a result, the wavenumber value for light having a wavelength of 7.20 m is roughly 1388.9 cm-1.

Question 3
After a landfill is closed, how much soil should be placed on top of the site?
a. two feet
b. six inches
c. four feet
d. as much soil in available
After a landfill is closed, a final cover system is put in place to reduce water infiltration, control odors, and prevent erosion. As part of this cover system, a minimum of two feet (or 0.6 meters) of soil should be placed on top of the landfill site.
OPtion A is correct
This soil layer helps to provide a barrier between the waste and the environment, as well as to promote vegetation growth on the site.
A landfill is a designated area where waste materials are deposited and buried in the ground. Landfills are typically used for the disposal of non-hazardous solid waste, such as household and commercial garbage, construction debris, and industrial waste. The waste is typically compacted and covered with soil or other materials to help prevent the spread of odors, litter, and potential environmental hazards such as pollution and contamination of groundwater.

After a landfill is closed, at least four feet of soil should be placed on top of the site to help reduce the risk of environmental contamination.
This soil cover helps to limit the amount of rainfall that enters the landfill, which in turn reduces the potential for leachate and other pollutants to seep into the surrounding environment. Additionally, the soil cover helps to limit the amount of odor and dust that can be generated from the landfill site. While more soil can be added if available, at least four feet is considered the minimum amount needed for adequate coverage.
