Sand is often produced by four processes: weathering of continental granitic rock, weathering of oceanic volcanic rock, precipitation from water, and skeletal remains of creatures.
Sand is typically obtained from rocks on land. Rock is cracked into smaller pieces over time by weather conditions such as rain, ice, wind, heat, cold, and even plants and animals. Large boulders that split into smaller rocks could be the starting point of this weathering. The granite is eroded by water that enters fissures.
Sand arises from volcanic rock in regions where there are volcanoes. This explains why the Hawaiian Islands' beaches are different colors.

a. Sediment is deposited on the down-current side of the jetty because water moves slower in this location.
b. Sediment is eroded on the up-current side of the jetty because the water is starved of sediment in this location.
c. Sediment is deposited on the up-current side of the jetty because water moves slower in this location.
d. Sediment is eroded on the down-current side of the jetty because water is starved of sediment in this
The statements that describe what happens to sediment when a longshore current meets a jetty are sediment is deposited on the up-current side of the jetty because water moves slower in this location (Option C) and sediment is eroded on the down-current side of the jetty because water is starved of sediment in this location (Option D).
Jetty refers to a variety of engineering structures which are connected with rivers, harbor, and coastal works and are designed to influence the current or tide or to protect the coastline from waves (breakwater). Jetties impact longshore transport of sediment and ecological processes. Sediment is eroded on the down current side of the jetty, as water contains low concentrations of sediments at the location. On the other hand, sediment is deposited on the up current side of the jetty as water movement is slower at the location which allows the time for deposition.

Thunder and lightning are most frequently observed _____?
Thunder and lightning are most frequently observed in Congo Basin in Central Africa and in the mid latitude than in the tropics.
What are Thunder and Lighting?Thunder is produced when lightning strikes the air. The lightning discharge quickly heats and expands the air. The temperature of the air in the lightning channel may approach 50,000 degrees Fahrenheit, making it 5 times hotter than the sun's surface.
Thunderstorms are most common over regions where intense solar heating promotes positively buoyant air parcels and convection. The highest frequency of lightning happens over equatorial Africa, and other low-latitude land regions have relatively high lightning frequencies as well.

Explain how the deranged drainage system as found in Michigan develops. (Hint: whydoes it look deranged
Since Michigan's geography is still relatively new in terms of its geomorphic history, as was described in the Geomorphology unit, it has bizarre drainage patterns.
What does "disrupted drainage pattern" mean?When there is no discernible pattern to the rivers and lakes in drainage basins, the drainage system is said to be disordered. These can develop where there are thick limestone deposits because surface streams can enter the groundwater through caves and underground drainage systems.
How are drainage systems created?The drainage pattern is the shape that the lakes, rivers, and streams make in a specific drainage basin.

Which of the following methods is not useful in dating rocks?
Group of answer choices
A.carbon dating
B.Sm-Nd dating
C.U-Pb dating
D.K-Ar dating
K-Ar dating is not useful in dating rocks.
Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).
Potassium is a common element found in many materials, such as feldspars, micas, clay minerals, tephra, and evaporites. In these materials, the decay product 40Ar is able to escape the liquid (molten) rock, but starts to accumulate when the rock solidifies (recrystallizes).
The amount of argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material, and a number of other factors. These factors introduce error limits on the upper and lower bounds of dating, so that the final determination of age is reliant on the environmental factors during formation, melting, and exposure to decreased pressure or open air.

According to his "uniformitarian" proposal, the forces shaping the planet today have been at work continuously throughout its history.

Glaciers are classified into two types: mountain glaciers and continental glaciers. Mountain glaciers create distinct erosional and depositional topography. Flowing ice, like flowing water, follows the original topography and seeks the steepest path.
Plucking is the removal of entire rock chunks. Glaciers can shape landscapes by eroding or removing rock and sediment. They can erode bedrock using two methods: Abrasion: The ice at the bottom of a glacier is usually contaminated with bits of rock, sediment, and debris.
Glaciers form on land, and they are made up of fallen snow that gets compressed into ice over many centuries. They move slowly downward from the pull of gravity. The majority of the world's glaciers are found in the polar regions, such as Greenland, the Canadian Arctic, and Antarctica.

projections show true distance in all directions from a central point. (enter only one word per blank.)
Projections show that the true distance in all directions from a central point is infinity. This means that the point can be seen as having no boundaries when it comes to its distance from the point in all directions. While this may seem counter-intuitive, there is a mathematical truth behind it.
Mathematically, the concept of infinity is expressed as a number that is larger than any number, which can be expressed as a finite quantity. It is therefore impossible to measure the distance in all directions from a central point, since the number is infinite. For example, if you were to measure the distance from a point on a map, the number would eventually hit an infinite number, as it is not possible to measure the distance beyond that point.
The concept of infinity is also helpful when it comes to understanding the universe. Since the universe is believed to be infinitely large, it is impossible for us to measure the exact boundaries of it. In other words, if we were to measure the distance from a central point, the number would eventually hit an infinite number, since we can never measure the distance beyond that point due to the size of the universe.

The very large crystals of quartz, feldspar, and muscovite found in pegmatites form from the final crystallizing parts of a magma.
How do pegmatites' crystals grow to such enormous sizes?In comparison to the ions in the melt, the ions in water are far more mobile. They may move about freely and crystallize quickly as a result. This explains why pegmatite crystals enlarge so much. Extreme crystallization conditions can sometimes result in crystals that are several meters long and weigh more than a ton.
How do pegmatites make their crystals?Instead, a magma that was particularly rich in dissolved water led to the formation of a pegmatite's enormous crystals. The water made it possible for the required components to diffuse to the crystallization sites very quickly. Veins that appeared at the conclusion of the crystallization of a sizable intrusive mass frequently develop pegmatites.

Infiltration of water is a process by which water is moved downward into the soil. In sandy soil where there is a large number of pores, water moves faster than through clay soil where the number of pores is small.
Water pores on the ground in the form of rain and snow move into the subsurface soil and rock through the process of infiltration. To cater to the needs of the present world, underground water is becoming exhausted rapidly.
