As of 31 December 2018, there had been 150 tornado event days with 1169 total tornado reports for 2018. On average, each tornado event day had about ______ tornadoes reported.
Answer:
7.798
Explanation:
It is understood that as at 31 December 2018, there had been 150 tornado event days with 1169 total tornado reports for 2018.
Then the average will be a calculated as:
1169/150= 7.79. This is regarded as the average amount of tornado experienced in the days it took place.
We can then infer and say that on average, each tornado event day had about 7.79 tornadoes reported.
The Old Man of the Mountain was a rock formation on the side of Cannon Mountain in New Hampshire. Scientists believe it formed 200 million years ago when the mountain was covered in glaciers. New Hampshire is known for its harsh, snowy winters. In the 1920s, scientists started noticing large cracks in the face of the mountain. In 2003, the rock formation collapsed.
The picture on the left shows the rock structure before its collapse. The picture on the right shows how the rock structure looks today. (The ghost image shows the part lost in the collapse.)
Part A
Explain the geological processes involved in creating the Old Man of the Mountain rock formation.
Part B
What factors likely caused its collapse?
Part C
Explain how both gradual and fast changes to Earth’s surface contributed to the collapse of the Old Man of the Mountain.
Question 2
Niagara Falls is eroding. But the average rate at which it is eroding has changed over time because of human activity. This graph shows the total erosion of Niagara Falls starting in 1900. (The falls were eroding before 1900, but we’ll look only at the changes after 1900 for this study.)
Part A
Based on the graph, determine how many total meters the falls eroded from 1900 until 1910.
Part B
How many meters of the rock wall eroded between 1910 and 1927?

Explain the degree to which the shape of the population (or age-sex) graph for countries like Japan and regions such as Western Europe can be described as a pyramid. NOTE: This question CANNOT be answered in one sentence. **USE COMPLETE SENTENCES, & INCORPORATE THE QUESTION INTO YOUR ANSWER.** *
Answer:
Population pyramid is called the distribution of inhabitants of a country based on their age; Given that in most cases, children and young people outnumber the elderly and the elderly, this distribution is plotted in the form of a pyramid, with a wide base and a narrow tip.
Now, there are certain cases in which this pyramid does not occur, but rather it is about graphs that tend to be rectangular. This is the case of the nations of Western Europe and Japan, where there is a very low birth rate, that is, where few children are born per couple; and where life expectancy is very high, causing the elderly to live longer and increase their percentage with respect to the total population of the country.

Why is the Caribbean region a good place to examine the effect of Creolization?
Answer:
Creolization is a demographic and cultural process by means of which a certain population, with preexisting characteristics, is subjected to the influence of migratory currents from different parts of the world, from which populations come that, due to their quantity, end up modifying the conditions of the pre-existing population, generating an ethnocultural mixture that gives rise to a totally different national identity, which results from said mixture and interrelation.
In this sense, the Caribbean is one of the regions where creolization has had the greatest effects: in principle, the native nations that were there have received a clear influence from the European powers that conquered their territories, to which later the huge number of African slaves that they took to their colonies. Subsequently, new migratory currents, mainly from Asia, reached certain parts of the Caribbean, generating in the region a mixture that today means that their nations have their own ethnic and cultural components, derived from the interrelation between the cultures that settled in the region.
Heat flow and movement of rock material within Earth are directly responsible for which of the following?
Answer:
Formation of mountains and ocean basins.
Explanation:
Earth is an active planet. It has multiple layers, and in the second layer from the top a process happens that is crucial for pretty much everything that occurs on the surface. This process is the circulation of convection currents in the mantle. Basically, the cooler and denser material sinks while the hotter and less dense material is pushed up.
This process creates constant pressure on the crust, and it is the one responsible for cracking and creating tectonic plates that move around the globe. With the interaction of the tectonic plates and different types of plate boundaries, there are numerous different processes that happen on the surface, with the formation of mountains and ocean basins being some of them.
e aThe mountains form at places where plates collide. One plate moves below the other so the crust near the plate boundary goes up, gradually forming a mountain range. Ocean basins are formed where hee are divergent plate boundaries on land. The crust splits open as the plates move away, a gap is formed which is constantly widening, and eventually ocean waters fill in the spreading gap. Over the course of tens of millions of years, a new ocean will be formed.

Ocean and freshwater contamination are independent of human activity. Thus option C is correct.
What is the ocean?A continuous mass of salt water that's also enclosed in a sizable basin on the surface of the Earth is known as an ocean.
Among the many factors that contribute to freshwater contamination are industrial contaminants, waste, discharge from towns, factories, and farms, as well as sedimentation. Both factories and automobiles emit emissions that enter the atmosphere. This contamination is bad for every living being that is present.
Blooms have a severe impact on the ecosystem and human health, which hurts the local tourism and fishing industries sectors. Humans need to know what can be dangerous to the water body and avoid them. Therefore, option C is the correct option.

Over time, many trading posts established along the frontier slowed expansion into the West. were captured by American Indians. grew into towns and cities. were abandoned when explorers returned east.
Answer: grew into towns and cities.
Explanation:
Trading posts were established along the frontier to better take advantage of the fur trade. At first these were simply trading posts but then they grew into settlements overtime.
First the owners of the post needed employees and some had more than others so they built houses. These people needed necessities so general stores were built. Women sometimes joined the men, got pregnant and a family was started.
These activities and more as well as the fall in fur trade and the rise in agriculture led to these trading posts becoming permanent settlements that grew into towns and cities.

which feature are formed by river erosions check all that apply
Answer:
When the velocity of wind or water slows, eroded sediment is deposited in a new location. The sediment builds up in a process called sedimentation and creates fertile land. River deltas are made almost entirely of sediment that has eroded from the banks and bed of a river.
There are many landscape features specifically associated with rivers: V shaped Valleys - particularly in their upper parts, rivers often form V-shaped valleys whereas glaciers commonly form U-shaped valleys. The V-shaped valley is created by erosion. Meanders - the curves or bends of a river.

Which statement best describes the spread of Hinduism? Hinduism did not spread outside of its homeland in India. The spread of Hinduism had stopped by the beginning of the Vedic period. Hinduism spread throughout India and Nepal, and into Southeast Asia. Beliefs of Hinduism changed greatly when it spread into the Middle East.
Answer:
Hinduism did not spread outside of its homeland in India.
Explanation:
Hinduism is one of the oldest religions in existence and it is also one of the major religions by having a very large number of followers. This religion is considered a national religion as well, and this is due to the fact that almost all of its followers live in one nation. Basically, this religion emerged in the Indian subcontinent and remained there.
Hinduism is the only polytheistic of the major religions. It came to be because of the mixing of the cultures and religious beliefs of the native Dravidians and migrating Aryans. By merging both religions, Hinduism arose and spread out all over the historic territory of India. With the rise of Islam, Hinduism lost some of its followers, mostly in what is now Pakistan and Bangladesh, while its followers remained almost exclusively in modern day India. Unlike the other major religions that managed to spread out of their cradles in one way or another, Hinduism did not.

Deep underwater, blue and green light dominated. How did this fact influence the appearance of early plants?
Answer:
Living off the colors of light available to them, bacteria in deeper water were green. Over time, these green bacteria grew to dominate the oceans and are considered early ancestors of today’s plants.
Explanation:
Sample Answer
Bacteria in deeper water were green, surviving on the colors of light that were available to them. These green bacteria are thought to be the earliest ancestors of modern plants and over time, they expanded to fill the oceans.
What is Bacteria ?
Bacteria are common, largely free-living organisms that frequently only have one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Bacteria, which are typically a few micrometers long and were among the first life forms to appear on Earth, are found in the majority of its habitats.
Water (often ocean water, but this also applies to fresh water) absorbs light, which changes which color wavelengths are present at certain depths. Reds, oranges, yellows, and purples disappear from the visible spectrum within the first 30 feet, leaving only blues and greens to reach the deeper waters.
Green plants can no longer operate at any depth greater than 10 feet since they depend on reds and oranges for photosynthesis. Consequently, a plant's ability to engage in photosynthesis depends on its color.

They measure the difference between arrival of P waves and S waves.
They draw circles around the epicenter from three locations.
They obtain information about the intensity of earthquakes from seismographs.
Answer:
The second one (s and p waves)
Explanation:
They use seismographs to measure intensity, but the differences of s and p waves can allow them to locate the origin
One step that geologists use to find the epicenter of an earthquake is B. They measure the difference between the arrival of P waves and S waves.
The epicenter of an earthquake refers to the point where the largest damage was done.
To determine the epicenter of an earthquake three seismographs are used. The time is measured that notes the arrival of the P and S waves.
The longer it takes for these waves to arrive, the farther the epicenter is from the point where the measurement is being taken.

The headwaters of a river are at an elevation of 1,229 feet and the river flows 373 miles to the ocean. Determine the river's average gradient in ft/mi. Give your answer with 2 decimals.
Answer:
3.29ft/mi
Explanation:
The gradient of a river is the slope through which a river flows. It measures the vertical drop in elevation of river to the horizontal distance.
Mathematically;
River gradient = [tex]\frac{Elevation}{horizontal distance}[/tex]
Elevation = 1229ft
Horizontal distance = 373miles
River gradient = [tex]\frac{1229}{373}[/tex] = 3.29ft/mi
