Explanation:

which of the following is not climate control
- latitude
-altitude
-longitude
-distance from oceans

Answers

Answer:

The answer is longitude

All the above except longitude are the climate control factors. The climate of any particular place is influenced by a host of interacting factors. These include latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds. The global climate system and any changes that occur within it also influence local climate.

Thank you and please rate me as brainliest as it will help me to level up

The distance east or west of the prime meridian is known as longitude. Longitude is defined by imaginary lines that circle the Earth vertically (up and down) and intersect at the North and South Poles.

So, Option C is the correct option as this is only the option that is not climate control.

The other options are incorrect as:

Option A is incorrect as Every climate has fundamental control over latitude. The seasonal variation in solar intensity has an impact on temperature. It has an impact on precipitation in the same way that evaporation is affected by temperature.

Option B is incorrect as altitude is also a climate control factor within one of the 7 factors.

Option D is incorrect as Oceans heat and cool at a considerably slower rate than land. This indicates that, at the same latitude and height, coastal sites are cooler in the summer and warmer in the winter than inland locations.

Thus Option C is the only factor that is not climate control.

Using complete sentences, describe the similarities and differences between the Clovis and Folsom cultures.

Answers

Answer:

The Folsom hunted mammoth, and the Clovis hunted bison. C. The Folsom were farmers, and the Clovis were hunter-gatherers. ... The Folsom used smaller and more refined spear points than the Clovis.

Explanation:

"Clovis & Folsom Cultures

Paleo-Indian points found in Nebraska, ranging in age from 8,000 to 11,500 years old

Paleo-Indian points found in Nebraska, ranging in age from 8,000 to 11,500 years old

Courtesy Nebraska Game and Parks Commission, ARCH02_KB0003_02

The oldest known Indian tool found in Nebraska is the Clovis point, made about 10,000 B.C.E. It is a spear point with a groove or flute, at its base. Attached to a shaft, this spear point was capable of penetrating an elephant’s hide. The Clovis culture takes its name from the town in New Mexico where the striking stone projectile point characteristic of this culture was first found. The chipped flint points known as Clovis points and a variety of additional stone tools artifacts are dated from 10,000 to 9,000 B.C.E. Its distinctive characteristics include a central groove, or flute, along both of its faces and finely worked edges.

The Folsom culture takes its name from Folsom, New Mexico. The artifacts recovered at this site included chipped flint points and a variety of other stone tools. The remains of large mammals, particularly extinct varieties of bison, were also found at this site. The remains date from 9,000 B.C.E. and 8,000 B.C.E. (or 11,000 to 10,000 years ago).

Bisonte Magdaleniense polícromo -- wikipedia images

These points were actually integral parts of a weapons system. Points were usually fastened to a short foreshaft, and then that foreshaft was inserted into the body of the lance. When they were hunting big game like the mammoth, Clovis and Folsom people would probably thrust the weapon into the animal, breaking off the foreshaft. The sharp point and foreshaft would then be free to do further damage to internal organs, speeding the kill. Toward the end of the period, they also began using the atlatl, a hand-held throwing stick that increased the power of the spear.

Two of the Paleo-Indian point types, Meserve and Scottsbluff, were first found at, and named for, locations in Nebraska. Many other types of spear points have also been found in Nebraska — Plainview, Folsom, Hell Gap, Agate Basin, Alberta, Eden, Frederick, Lusk, and Brown’s Valley. Sites abandoned by some of these Paleo-Indian cultures have been excavated in western Nebraska."

True or False: Members of the Wampanoag tribe helped the colonists survive.

Answers

Answer:

True, members of the Wampanoag tribe helped the colonists survive.

Explanation:

When the colonists first arrived in what is now Massachusets, they didn't really know what they're facing and were simply not aware of the conditions in the area and how to survive long term. This was a big problem because the reason why they moved there was because of searching for new opportunities and by not surviving this wouldn't have happened, while the government had its goal on long term settlements through which it will increase its influence in the region.

The reason why the colonists, referred to as Pilgrims, survived were the members of the native Americans, namely the Wampanoag. The Wampanoag were friendly and they explained to the colonists what they can expect climate-wise, thought them about the characteristics of the land, introduced them to local crops and how to grow them so that they can feed themselves. This led to good and friendly relations between the two groups and the colonists survived and managed to remain in the area.

Describe the weather phenomenon El Niño and La Niña in your own words.

Answers

The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. La Niña episodes represent periods of below-average sea surface temperatures across the east-central Equatorial Pacific. Global climate La Niña impacts tend to be opposite those of El Niño impacts. In the tropics, ocean temperature variations in La Niña also tend to be opposite those of El Niño. Hope this helps!

Answer:

An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.

Minerals are fundamental components of rocks and have great economic and commercial significance to humans. Therefore, geologists need a set of characteristics to identify and describe what makes an object a mineral versus something synthetic (such as plastic, for example). The criteria that defines matter as a mineral is that it is inorganic, composed of an orderly crystalline structure, solid, naturally occurring, and can be expressed by a chemical formula. Some matter looks very similar to minerals, but does not quite meet the criteria. For example, consider glass and quartz. Both are transparent and can have similar appearance. Glass does not have an orderly internal structure; its silica atoms are randomly arranged. Thus it is not a mineral. Quartz, however, has an organized chemical structure of silica atoms, each surrounded by four oxygen atoms and is a mineral.

Mexico was a colony of Spain and at the time of the colonization of the New World Spain was highly Catholic, now the Mexican population are also highly Catholic due to the spreading of Catholicism during Mexicos colonial days. The merge of Settlers and Natives also created a new mix of population and a more diverse community.

What are the four basic movements of the Earth?

Answers

Answer:

The Earth turns (rotation around the polar axis), goes along on its orbit (revolution around the Sun), swings smoothly as un unbalanced spinning top (equinoctial precession). As long as you live on the Earth, these motions remain imperceptible.

Explanation:

The rotation, revolution, precession, and movement of the Earth in conjunction with the solar system are all examples of Earth movements.

What is an earth movement?

Earth Movement refers to any surface-level movement or vibration (other than "sinkhole collapse"), including but not limited to earthquake, landslide, mudflow, mudslide, mine subsidence, or earth sinking, rising, or shifting.

Earth moves in two directions. It revolves around the sun while spinning. Rotation refers to the earth's rotation. The earth makes one full rotation in about 24 hours, or one day.

The rotation, revolution, precession, and movement of the Earth in conjunction with the solar system are all examples of Earth movements. The primary result of rotation, which is the Earth's movement around its axis and lasts for about 24 hours, is the alternation of day and night.

Why is Greenland’s ice sheet melting more than Antarctica?

Answers

Answer:

Every centimeter of sea level rise leads to coastal flooding and coastal erosion, disrupting people's lives around the planet," said Shepherd. As to what is leading to the ice loss, Antarctica's outlet glaciers are being melted by the ocean, which causes them to speed up.

Explanation:

An increased rate of mass loss results in a faster rise in the global mean sea level.  Owing to gravitational forces, the melting of the Antarctic ice sheet contributes more to sea level rise in the northern hemisphere than the melting of the Greenland ice sheet.

What is the global distribution of megacities

Answers

Answer:

global distribution of megacities refers to the dispersion of a population of 10 million people or more in all parts of the world.

Explanation:

Global distribution  of megacities is usually determined by the number of people within a population which should not go below 10 million. these people making up the populations can be located in different locations, either in the cities or in the countryside. In January 2015, for example, China’s Pearl River Delta conurbation overtook Tokyo as the world’s largest city (Van Mead, 2016). However, this depends on how the ‘city’ is measured – the Pearl River Delta includes the cities of Shenzhen, Guangzhou, Foshan and Dongguan (but not Hong Kong, which is considered a separate territory under its ‘Special Administrative Zone’ status within China). If these cities were measured separately, Tokyo would likely remain the world’s largest city.
