Do volcanic eruptions and asteroid impacts may have brought warm or cool climates?
Yes.
Very powerful volcanoes can blast millions of tons of dust and ash high into the stratosphere, where it reflects a substantial fraction of the Sun's light and heat back into space. These happen every couple of centuries, and the weather gets several degrees colder for a year or two. VERY large eruptions can darken the sky for decades, and may be the cause of some ice ages.
Asteroid impacts can have similar effects. For example, something big struck northern Canada about 15,000 years ago, and the resulting mini-ice age called the Younger Dryas probably caused most large animals in North America and Siberia to become extinct, including the mammoth and mastodon, and the saber-toothed tiger. It also killed off the American aboriginal humans known as the "Clovis People" who had inhabited North America before that time. The "Native Americans" were a later migration from Asia a few thousand years later.

Who was the Carthaginian general that brought elephants across the Alps to attack Rome?
Hannibal invaded Italy. He brought 32 elephants with him. The elephants were war elephants and were brought to use them to attack the Roman armies, not to cross the Alps, which was a difficult feat for these animals which were gigantic and from very hot climates. Most of his elephants (if not all of them) died while crossing the Alps in the snowy winter.
What is the duration of Brought by the Sea?
The duration of Brought by the Sea is 1.78 hours.
What type of clothing did the Apache wear?
__________________________________________________________ The Apache were a south-western tribe who wore clothing adapted to the hot desert climates of New Mexico, Arizona, and the surrounding areas. Men wore little clothing outside of a loincloth and moccasins on a regular day. Women often wore light-weight, blanket-like clothing with moccasins. Cold nights brought out woven blankets for either gender.
How was western heritage brought to Africa?
The Brittish brought it over when they were looking for slaves.
Which prime minister brought home the confederation from Britain in 1982 in Canada?
No PM brought home confederation. However Trudeau brought the Constitution home to Canada.
Can eruptions affect aircraft?
In 2010, a volcanic eruption in Iceland brought much of Eoropean air travel to a halt. The increased levels of ash were bad for visibility nad plane engines.
Why is the short tailed albatross threatened?
Because of longline fishing and volcanic eruptions on Torishima. It also has a small breeding ground and limited diet so its very vulnerable. It was brought close to extintion by feather trade.
How did volcanic eruptions and comets change early earth?
Volcanic eruptions and comets both contributed to bringing water and other gases to Earth's surface creating the atmosphere. Volcanic products created nutrient rich soils for plants to grow and if the comets were large enough, they could create large enough indentations for lakes and oceans to form.
What often accompany eruptions and can be brought on by heavy rain?
mudslides
What diamonds are in volcanoes?
Diamonds found in volcanoes are typically formed deep within the Earth's mantle under high pressure and temperature conditions. They are brought to the surface during volcanic eruptions through volcanic pipes called kimberlite pipes or lamproite pipes. These diamonds are known as "kimberlite diamonds" or "volcanic diamonds".
What landform are diamonds found?
Diamonds are typically found in kimberlite pipes, which are cone-shaped volcanic rock formations that form deep in the Earth's mantle and are brought to the surface through volcanic eruptions. Diamonds can also be found in alluvial deposits, where they have been eroded from the original source rock and are concentrated in riverbeds or coastal areas.
How do xenoliths and xenocrysts reach the surface?
Xenoliths are rock fragments that are brought to the surface during volcanic eruptions, carried within the magma from the Earth's mantle. Xenocrysts, on the other hand, are crystals that form deep within the Earth and are also brought to the surface during volcanic eruptions through the magma's ascent. Both xenoliths and xenocrysts provide valuable information about the composition and processes occurring in the Earth's interior.
What are lumps that have compositions different from the main body of rock called?
Those are typically referred to as xenoliths. Xenoliths are rock fragments that have different mineralogy and composition compared to the surrounding rock which they are found in. They are often brought to the surface during volcanic eruptions.
How a diamond reaches earth?
Diamonds are formed deep within the Earth's mantle under high temperature and pressure conditions. They are brought to the surface through volcanic eruptions, where they are found in volcanic pipes or kimberlite deposits. These diamond-bearing rocks are then mined and the diamonds are extracted for various uses.
What is Kimberlite Magma?
Kimberlite magma is a rare type of volcanic rock that is known for containing diamonds. It is derived from the Earth's mantle and is typically generated during deep-source volcanic eruptions. Kimberlite deposits are important for diamond mining, as they carry diamonds to the surface from deep within the Earth.
Where is diamond in the rock cycle?
Diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions, making them one of the final stages in the rock cycle. They are brought closer to the surface through volcanic eruptions and can be found in kimberlite pipes or alluvial deposits.
Where are diamonds usually found on earth?
Usually, diamonds are found on earth around volcanic pipes -- the core of diamond mines, or downstream from volcanic pipes -- alluvial diamonds -- when flowing water rolls diamond stones away from the pipes where they erupted to the earth's surface.
