Loess is assumed to have primarily glacial and periglacial origins in Europe and North America.
Where does loess come from?Loess is created primarily by wind and is also formed by glaciers. Glaciers can turn rocks into a fine powder, which can lead to the development of loess. Streams carry the glacier's terminus's powder. This sediment is converted into loess.
Loess was formed in North America from both glacial and nonglacial causes, but it is often connected to the floodplains of large, braided rivers and to the outwash deposits of the Laurentide ice sheet; parts of the Mississippi River basin may have loess up to a depth of 20 meters.
Why is loess essential and how does it form?The majority of loess is made up of coarse silt-sized quartz particles with a diameter of 20–63 m, however certain desert loess deposits can contain fine sands with an 80 m or less diameter. Loess is made up of large amounts of wind-blown dust that have been captured, laid down, and preserved on specific terrain.

When a river enters an ocean and begins deposition sediments to form deltas, the first particles to settle out are large particles and sand followed by _____ and _____, which settle farther offshore
silt; clay
Large particles and sand are the first particles that settle out when a river meets an ocean and starts depositing sediments to form deltas, followed by silt and clay, which settle further offshore.
What materials are the first ones to end up in a river?Sediment builds up in the water as a river slows down. Larger, heavier particles like pebbles, sand, and other materials settle first; lighter ones like silt and clay don't settle until the water is almost still.
What occurs when sediments are released by sand particles after they have settled out of the ocean or wind?This so-called detritus material is made up of rock and mineral fragments. When the energy of the carrying current is not enough to carry the particles, they fall out during the sedimentation phase. The word used to describe this process of sedimentary deposition is clastic sedimentation.

HELP Using information from the article and the lesson, as well as your understanding of Japan’s physical terrain and population patterns, explain why the country has become more reliant on railways rather than roadways. What evidence can you point to in support of your explanation?
Since the late nineteenth century, trains have remained the primary mode of passenger transportation in Japan. Government policy encouraged railroads as an effective mode of transportation for a nation lacking fossil resources and heavily reliant on imports.
What is Transportation in japan?Japan has invested a lot of money in its highways. The primary mode of transportation in japan is the 1.2 million kilometers of paved roads. Traffic in Japan is left-handed. Major cities are connected by a single platform of toll roads that are divided into several lanes and have limited access and are run by businesses that collect tolls.
The primary means of transportation in japan around the nation is via rail, which provides quick and regular transit within and between large metropolises.

Answer:
Japan’s mountainous terrain has led to a clustering of large populations along the coastline, often around seaports. This greater concentration of people along the coasts makes public transportation in the form of metro trains more efficient than roadways. Roads would clog up with cars in a city like Tokyo if people drove themselves to and from work or school each day. According to the article, Japan has no fossil fuels to operate cars, so a more efficient transportation vehicle, like a train, was needed to use natural resources wisely. Also, crowded roadways have led to car accidents, encouraging more people to use the safer transportation option of trains.

a) It's elliptical galaxy
b) Spiral galaxies appears to contain more young, hot, massive stars
Researchers accept that elliptical galaxies are the absolute most established systems known to mankind and hence the most developed of the three universe types. Elliptical galaxies, which have either a round or cucumber-like shape, address almost 33% of worlds in the universe. Mature stars that have spent most of accessible residue and gas in the universe structure this circular shape. Furthermore, elliptical galaxies are portrayed by stars that turn in arbitrary circles.
Thus, elliptical galaxies have next to no residue and gas, some of the time causing them to seem faint contrasted with other system types. A black hole alludes to a district of room where a solid gravitational field keeps matter and light from getting away.
A spiral galaxy commonly has a pivoting circle with winding 'arms' that bend out from a thick focal district. The Milky Way is a spiral galaxy.

Currently, average sea surface temperatures are decreasing across the globe.
a. True
b. False
This claim is untrue. Globally averaged sea surface temperatures are not currently dropping.
Is the surface of the ocean getting warmer or colder?The average SST for the entire planet has increased since the start of the industrial period. Although it has not been constant across time or space, the average global increase in SST over the past four decades has been roughly 0.6°C.
Despite some year-to-year variability, the sea surface temperature has consistently increased over the past three decades more than it has at any other point since reliable data began in the late 1800s. Despite this, there is a noticeable increase overall.
Why is the temperature of the sea rising?Rising levels of greenhouse gases are making it harder for heat radiated from the Earth's surface to escape into space as easily as it formerly did. The majority of the extra atmospheric heat gets returned to the ocean. Because of this, the top ocean heat content has considerably grown during the previous few decades.

The Sierra Nevada and Sawtooth mountain ranges were caused by a huge intrusion type known as a ________.
The correct answer is Laccolith The Sierra Nevada and Sawtooth mountain ranges were caused by a huge intrusion.
When magma (molten rock) rising through the Earth's crust starts to spread out horizontally and tear apart the host rock strata, a laccolith is created. The laccolith's dome-like shape is the result of the overlaying strata being driven higher by the magma's tremendous pressure. A laccolith is a mass of igneous or volcanic rock found inside a stratum, whereas a batholith is a sizable irregular mass of intrusive igneous rocks that pushes itself into the surrounding layers. Igneous rocks and volcanic landforms include batholiths and laccoliths in their composition. In terms of geology, a laccolith is any igneous intrusion of a certain type that has broken apart two strata and produced a dome-shaped structure; the floor of the formation is typically horizontal.

determine which part of a hurricane is the strongest, and describe which parts of a coast will be most impacted by a hurricane.
The strongest and most hazardous region of the storm, known as the eyewall, is located just outside the area where it is calmest. Within a hurricane, this is where the greatest winds are located. As you get out from the storm's eyewall, the winds significantly lessen.
The storm's strongest winds are located in the thick wall of thunderstorms encircling the eye. Wind speed, a measure of the storm's strength, can alter due to changes in the eye and eyewall's structure. However, they can travel throughout the Atlantic Basin anywhere between the northern Bahamas and Atlantic Canada, in the Gulf of Mexico, the eastern Caribbean Sea, and the western tropical Atlantic.
Tropical storms and hurricanes most regularly form off the Southeast and mid-Atlantic coasts (to the east of the Lesser Antilles). The storm's right flank and frequently its right-front quadrant relative to its forward motion are where the strongest winds are almost always found. Therefore, the extent of the wind field in each quadrant will depend on the storm's forward motion, both in terms of direction and speed.

The system of equation that can be used to find how many pounds of each fruit Sam bought include:
x + y + z=30
x + 2y + 3z = 46
x = 2y+2z
How to illustrate the equation?let x = Number of pounds of bananas
y = Number of pounds of guavas
z = Number of pounds of dragon fruit
According to the question,
x + y + z = 30 (i) (total fruits bought = 30 pounds)
Bananas cost $1 per pound; guavas cost $2 per pound; and dragon fruit costs $3 per pound and total cost = $46.
∴ x + 2y + 3z = 46 (ii)
Also, weight of the bananas = 2 (weight of the guavas + weight of dragon fruit)
∴ x = 2(y + z)
⇒x = 2y + 2z (iii)
from (i), (ii) and (iii)
x + y + z=30
