Which of the following statements is true?
A. Glacial erosion forms wide, U-shaped valleys.
B. In saltation, acids and salt in ocean water can dissolve rock minerals.
C. Mass wasting happens when sediment is carried from a low elevation to a high one.
D. Mudflows are the least dangerous type of sediment flow
Glacial erosion forms wide, U-shaped valleys is the true statement.
In essence, glaciers are substantial ice masses that are either created by massive amounts of snow or a frozen river. The glaciers contribute significantly to erosion since they not only appear at higher locations and slowly travel towards lower ones as the ice expands.
The glaciers modify the terrain according to their shape, which is an extended, river-like U-shape, by eroding large amounts of material due to their size, weight, movement, and pressure.
The long, narrow U-shaped valleys that the glaciers leave behind after melting are divided into those that are left as valleys and those that are filled with seawater to form fjords.

Describe how the size and color of granite sediments change when they are exposed to rain and wind?
The most crucial component of sediment movement is water flow, commonly referred to as water discharge. Sediment is gathered, transported, and dumped in a canal by the flow of water. Sediment may remain suspended as well as settle out in the absence of flow, but it would not migrate downstream.
Chemical weathering of granite occurs when dilute carbonic acid, and other acids present in rain and soil waters, alter feldspar in a process called hydrolysis. Weathering is a time period which describes the overall procedure via way of means of which rocks are damaged down on the Earth’s floor into things like sediments, clays, soils and materials which might be dissolved in water.
The procedure of weathering usually starts off evolved while the earth’s crust is uplifted via way of means of tectonic forces. After the bodily breakup and chemical decay of uncovered rocks via way of means of weathering, the loosened rock fragments and changes merchandise are over excited via the procedure of erosion.
Erosion is based on transporting dealers consisting of wind, rivers, ice, snow and downward motion of substances to hold weathered merchandise far away from the supply area. As weathered merchandise are over excited, clean rocks are uncovered to in addition weathering. Over time, that mountain or hill is step by step worn down.

Why can't the dark matter in galaxies be made of neutrinos?
Neutrinos travel at extremely high speeds and can escape a galaxy's gravitational pull that s why dark matter in galaxies is made of neutrinos.
What Are Neutrinos?Neutrinos are incredibly small, almost massless particles that move at speeds close to the light. They are incredibly numerous in the universe and can flow through lead as readily as we do through air. They were created by intense astrophysical events like exploding stars and gamma-ray bursts.
However, the most prevalent particle in the universe is the neutrino. Unbelievably, your body is exposed to about 100 trillion neutrinos every second(opens in new tab)!
It is exceedingly challenging to detect neutrinos due to their tendency to interact with other particles seldom; nevertheless, this does not imply that they never do; rather, the likelihood of any given neutrino interacting with another particle is only very low.

If a clock on a ship indicates that it is 2:00 P.M. in its home port, while another clock on the ship indicates that it is 12:00 noon at the ship's present location, what is the difference in longitude between the ship's position and its home port
The longitudinal system establishes a distance -in degrees- from the Greenwich Meridian to any random point on the Earth's surface. Option D: The ship is 30 degrees west of its home port.
What is the longitudinal system?The longitudinal system is a way to measure the distance in degrees between a random point on the Earth's surface and the Greenwich Meridian.
The Greenwich Meridian divides the Earth's surface into two halves.
The half on the left is the Eastern Longitude (oriental hemisphere)The half on the right is the Western Longitude (occidental hemisphere)
The Greenwich Meridian is always at 0º longitude.
Hence, longitude is always measured from the Greenwich Meridian to the west or the east.
There is a relationship we can establish between time and longitude to determine the distance in degrees or in hours between two points on the Earth's surface.
We know that the Earth completes a whole spin equal 360º in 24 hours. So, the relationship between time and degrees is as follows,
24 hours / 360º = 1hour / 15º.
If we know the difference in time between one point and the other one, we can calculate the distance in degrees between these two point.
In the exposed example,
Home port ⇒ 2:00 P.M ⇒ 14:00Ship's position ⇒ 12:00Difference in time ⇒ 14:00 - 12:00 = 2 hours
Now, we can calculate the distance in degrees by using the previous relationship,
1 hour ------------- 15º
2 hours----------- X = 30º
Since this relationship is concernig the Greenwich Meridian, the difference in longitude between the ship's position and its home port is 30º West.
Option D is correct. The ship is 30 degrees west of its home port.

As they approach North America, hurricanes commonly move north on clockwise-curving paths due to the:- Coriolis effect
Coriolis effect
An effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclonic weather systems.The key to the Coriolis effect lies in Earth’s rotation. Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.

Why does the intensity of solar radiation striking earth's surface change when the sun angle changes?
When solar radiation strikes Earth at lower angles, it is more dispersed and less intense, while when it strikes Earth at higher angles, it is more concentrated and intense.
When the Sun's rays hit Earth at greater angles, their courses are shorter; when they hit Earth at lower angles, their paths are longer. The amount of solar radiation reaching Earth's surface is lessened by these longer pathways.
The irradiance incident on an absorbing surface has the largest power density when the Sun's beams are perpendicular to that surface. The intensity of light on the surface decreases as the angle between the sun and the absorbing surface varies.
The intensity of light decreases to zero when the surface is parallel to the sun's beams (making the angle from perpendicular to the surface 90°). This is because the surface is not hit by the light.
The angle between the Sun's beams and the direct normal (or perpendicular) to the surface is, and the relative power density at intermediate angles is cos(), where is the angle.

Which zone changes the least with latitude?
Answer:
Multiple Choice littoral O epipelagic O abyssal neritic photic < Prey
The zone that changes the least with latitude is the abyssal zone as it is located in deep ocean and is not influenced much by surface factors.
Hence, the correct answer is option c.
The abyssal zone is a region of the ocean depths, typically between 3,000 and 6,000 meters (9,800 to 19,700 feet) below the surface. This zone is characterized by extremely high pressure, low temperatures, and complete darkness. Since the abyssal zone is found in the deep ocean, far from the influence of surface factors, it experiences relatively little variation with latitude.
The physical conditions, such as temperature and light availability, remain fairly constant throughout the abyssal zone regardless of its latitude. In contrast, other zones mentioned such as the littoral, epipelagic, neritic, and photic zones are more influenced by latitude and exhibit greater variability in environmental conditions, including temperature, light penetration, and species diversity, as they are closer to the ocean surface and affected by factors such as solar radiation and proximity to landmasses.

At a convergent margin, an oceanic plate collides with a continental plate, driving the oceanic plate under the continental plate and destroying it. This is the main distinction between oceanic-oceanic convergence and oceanic-continental convergence. At the convergent boundaries, the continental plates thicken and migrate outward. The thickness of continental plates is much greater than that of oceanic plates.
This is further explained below.
What are continental plates?Generally, The North American Plate is an example of a continental plate since it encompasses not only North America but also the oceanic crust that lies between it and a piece of the Mid-Atlantic Ridge. This makes the North American Plate both continental and oceanic plate.
In conclusion, The most significant distinction between oceanic-oceanic convergence and oceanic-continental convergence is that at a convergent margin, an oceanic plate collides with a continental plate, burying the oceanic plate beneath the continental plate and obliterating it in the process. Oceanic-oceanic convergence occurs when two oceanic plates collide with each other. The continental plates are pushed further apart from one other, and the margins where they converge get thicker.
