Ice Ages

The environment in the Northeastern part of the Americas changed after the ice age ended. The climate of the Northeast became warmer, and there was less big game to hunt, but crops were plentiful.

Pioneer species are the first organisms to colonize a barren landscape following a disturbance like glacial retreat. These species are typically well-adapted to harsh conditions and are essential in the process of ecological succession, paving the way for other species to establish themselves. Over time, pioneer species help transform the environment and create conditions suitable for more diverse plant and animal communities to thrive.

Land bridges aren't actually formed, they are already there but covered by the sea.

When a glacial period starts, the water evaporated from the oceans falls as snow on the land and then compacts as ice which does not melt. Continual removal of water from the oceans over thousands of years causes sea level to drop and exposes the "land bridges".

The Earth's orbit doesn't change enough to make ANY changes in climate likely. Orbit can be predicted accurately over thousands of years and has not changed. If orbit did change, it wouldn't change for only a year and then return to normal; it would change indefinitely.

The current theory isn't that it's the earth's orbit that changes, but rather that there are regular changes to the angle of inclination on earth's axis. It's currently 23 degrees, but a lesser angle would mean cooler summers across the globe. In the northern and southernmost latitudes, this would mean that the previous winter's ice wouldn't completely melt prior to the next cooling season. Over time, this would result in significant glaciation, until the inclination of earth's axis moved back to 23 degrees.

The above argument that changes in the earth's orbit ended the last ice age isn't plausible. The earth moves in a slightly elliptical orbit, and is about a million miles closer to the sun in January than it is in July.

Obviously they survived! What do you actually mean?

They had a long struggle, kept warm,snuggled up in firs with each other, slept with the dogs, ate meat, built fires, grunted at each other and waited for the SPRING AGE!

The earth is roughly 4.5 billion years old. We know this to be the case because we have dated rocks from the moon that old, and earth must be at least as old as our moon.

It can do this in two ways.

# The Ice can hold rocks in itself and rub these (like sandpaper) across other rocks as it moves, this causes the rocks being rubbed together to break.This is called abrasion.

# It can also break rock as it freezes, this is because when water freezes it expands and thus if water enters a crack in a rock then freezes in the crack the ice will try to force the crack open and over time this breaks up the rock. This is called freeze-thaw.

The ice age is important as it shaped the landscape, influenced evolution, and affected human migration patterns. It also played a role in shaping present-day ecosystems and climate systems. Understanding the ice age helps us comprehend past climate changes and their impacts on Earth's environments.

The current interglacial period is known as the Holocene epoch, which began about 11,700 years ago after the last major glacial period. It is characterized by relatively stable climate conditions compared to the glacial periods.

Strictly speaking the most recent Ice Age started about 2.6 million years ago and we are now in an interglacial period,(warm period), during the Ice Age.

The last glacial period started 115,000 years ago and finished about 10,000 years ago, though there were a number of warmer periods during that time.

During the ice age, ocean levels were lower than they are currently due to a significant amount of water being locked up in glaciers and ice sheets on land. This resulted in larger land areas being exposed and connected, enabling the migration of species between continents.

The region located between 23.5 degrees north and south of the equator is known as the Tropics. This area experiences high temperatures and receives direct sunlight throughout the year due to its position near the equator.

It shaped much of New England.

Huge amounts of gravel were pushed around, creating Long Island.

It covered Canada under thousands of feet of ice.

"Ice Age: The Meltdown" is the second movie in the Ice Age franchise, specifically the sequel to the original "Ice Age" film. The movie follows the adventures of Manny, Sid, and Diego during a time when the prehistoric world is experiencing a massive meltdown due to climate changes.

Yes. Ice Ages are real, and have happened fairly often in Earth's history, including nine "major" ice ages and scores of "minor" ones in the past 800,000 years.

The most recent minor ice age lasted from about 1350 to about 1850.

You can see graphs of the major events and some of the minor ones at the linked site about Greenland.

Precession is related to the Ice Age in the sense that it helps propagate and is line with the Ice Age's theory about astronomy, especially pertaining to the earth's orbital forces and the rotation of the earth's axis.

Methane gas likely played a role in warming the Earth after the last ice age by contributing to the greenhouse effect. However, it was not the sole factor responsible for the end of the ice age. Other factors such as changes in Earth's orbit, solar radiation, and feedback mechanisms likely also played significant roles.

Kent gets a lot of snow because it is located in a region that experiences colder temperatures and frequent weather systems that bring snowfall, such as low-pressure systems and lake-effect snow from the Great Lakes. Geographic factors, like proximity to bodies of water and elevation, can also contribute to increased snowfall in the area.

During the last ice age, approximately 20,000 years ago, global sea levels were around 130 meters (426 feet) lower than they are today. This drop in sea level was due to a large amount of water being locked up in ice sheets covering much of North America and Eurasia.

Ice ages end due to a combination of factors, including changes in Earth's orbit, variations in solar radiation, and changes in greenhouse gas concentrations. These factors contribute to gradual warming of the climate, leading to the melting of ice sheets and the transition out of the ice age period.

There have been about 8-10 major ice ages in the past 800,000 years, occurring approximately every 100,000 years. These ice ages are characterized by periods of lower global temperatures and expanding ice sheets.
