Describe and explain the three reasons glaciers flow. please use complete sentences and proper grammar.
The bedrock has a slope, which causes the glacier to move downward as the first cause of glacial movement. Second, since ice crystals must bend to flow downward, the glacier's ice sheets help it do so. Ice sheets are created when ice crystals deform. Thirdly, the flow of melted water beneath the glacier is what causes it to move.
Why does Glacier flow occur?The weight and creep characteristics of ice have a straightforward effect on glacier flow. When ice is subjected to shear stress over time, it will creep, or plastically deform. Under constant shear stress, the rate of plastic deformation starts out quickly before tapering off to a constant amount.
A curved graph will be produced if this stable value, the shear-strain rate, is plotted against the stress for a wide range of applied stress values. The chart demonstrates the shear strain rate's near proportionality to the shear stress cube, which is the flow law or fundamental law of ice.
All assessments of the movement of ice sheets and glaciers are built around this fundamental law, which glaciologists frequently refer to as the Glen flow law.

For a given material, would you expect the surface energy to be _____________________ the grain boundary energy.
For a given material, would you expect the surface energy to be greater than the grain boundary energy.
Because the bonds between the atoms at the surface are considerably weaker than those at the grain boundary, surface energy is higher than grain boundary energy. Additionally, the quantity of bonds formed directly according to the energy.
In other simple words, atoms on the surface also have more rigid boundaries than atoms at the grain boundary. As is well known, the energy surface rises when there are no connections between the atoms. As a result, the surface energy vastly exceeds boundary energy.

Directly seaward of the continental shelf is a more steeply sloping region called the continental slope.
A continental slope is what?The slope from the continental shelf's outer edge to the deep ocean floor is referred to as a continental slope. Submarine canyons cut the continental slope over various areas. The seaward boundary of the continental shelf is marked by the continental slope.How is the slope of the continent formed?The continental slopes serve as transient locations for sediment deposition throughout geologic time. Rivers may immediately deposit their sedimentary burden on them during times of low sea level. As the mass becomes unstable from the accumulation of sediments, it sloughs off to the lower slope and the continental rise.To learn more about continental slope visit:

Machu Picchu is an ancient Incan citadel located approximately 80 kilometers (50 miles) south of Cusco, Peru. When the American explorer Hiram Bingham III first visited the settlement's ruins in 1911 and brought them to the world's attention, they were little known — even among Cusco residents.
Machu Picchu is a 15th-century Inca citadel located on a 2,430-meter (7,970 ft) mountain ridge in the Eastern Cordillera of southern Peru. [2] [3] It's in the Machu picchu District of Urubamba Province, above the Sacred Valley, about 80 kilometers (50 miles) northwest of Cusco. The Urubamba River flows past it, carving a canyon through the Cordillera and creating a tropical mountain climate. According to studies, the majority of the people who lived there were immigrants from various backgrounds. They lacked the chemical and osteological markers that would have been present if they had lived there their entire lives. Instead, bone damage was caused by various species of water parasites native to different regions of Peru. There were also varying osteological stressors and chemical densities, implying that the long-term diets of specific regions were spaced apart.

The act of removing infected plant parts (fallen twigs, leaves, and fruit) from a landscape in an effort to prevent a buildup of a pest population is known as Pruning.
What is Pruning?Pruning is a horticultural, arboricultural, and forestry technique that involves removing particular plant parts, like branches, buds, or roots, with care.The procedure entails selectively removing plant material from crop and landscape plants that is diseased, damaged, dead, ineffective, structurally unsound, or otherwise unwanted.Generally speaking, the easier it is for a woody plant to compartmentalize the incision and reduce the risk of pathogen penetration and decay, the smaller the branch that is cut. Therefore, it is preferable to prune young plants during their formative stages rather than removing big, awkwardly placed branches from adult plants.Deadwood removal, shape (by directing or limiting growth), enhancing or maintaining health, and lowering risk from falling branches are a few reasons why plants should be pruned.Learn more about pest population here:

How does the sediment in glacial till compare to the sediment being transported by the braided streams draining away from the terminus?
The main types of sediment in a glacial environment are described below. Supraglacial (on top of the ice) and englacial (within the ice) sediments that slide off the melting front of a stationary glacier can form a ridge of unsorted sediments called an end moraine. The end moraine that represents the farthest advance of the glacier is a terminal moraine. Sediments transported and deposited by glacial ice are known as till.
The sediment in glacial till compare to the sediment being transported by the braided streams draining away from the terminus as one is unsorted and stratified.
What is sediment?Rocks however little as small dirt particles and bigger ones that seem to be moved by the water are called sediment. Quick water can get, suspend, and move bigger particles more effectively than sluggish waters.
The Glacier sediment that is present is usually unsorted as well as unstratified. But when it comes to steam deposits these are the ones that are stratified and most certified this can be because of the draining and the flow of water that is present at that point in time.

Why are temperatures cooler in quito, ecuador, than in most other places located near the equator?.
Despite being close to the equator, Quito has a cooler climate due to its higher altitude. Higher latitude locations have a cool environment. This is because temperature drops as altitude rises.
Since Quito is so close to the equator, it is quite uncommon to get high pressure systems. Systems with extremely low pressure are likewise uncommon since pressure is steady.
Almost all of the western section, on both the plain and the coast, is impacted by a cool ocean current called the Humboldt current. This reduces the temperature a bit and makes the climate more arid. Andes crosses the center part and is therefore mostly cold depending on altitude.

An earthquake with a magnitude of 8.0 releases 32 times more energy than an earthquake with a magnitude of 7.0.
Magnitude is essentially a measurement of the overall energy released during an earthquake. How much and how far the rock moves determines how much energy is released. The amount of seismic energy released increases by around 32 times for every whole-number increase in magnitude.
While magnitude matters, the location of an earthquake's epicentre is crucial. The ones that affect the majority of people occur beneath or close to densely populated regions.
