Earth's ice ages are primarily thought to be caused by variations in the Earth's orbit and tilt, known as Milankovitch cycles. These cycles affect the amount and distribution of sunlight reaching the Earth, leading to fluctuations in global temperatures and the growth or retreat of ice sheets. Additional factors such as changes in greenhouse gas concentrations and volcanic activity can also influence the onset and duration of ice ages.
What else can I help you with?
Which is thought to be most responsible for earths ice ages?
Earth's precession
Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
What process is most responsible for the increase in early Earths atmospheric oxygen levels?
The process most responsible for the increase in early Earth's atmospheric oxygen levels is photosynthesis. This is the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen and energy. Over time, the accumulation of oxygen from photosynthesis led to the rise in atmospheric oxygen levels.
What is the earths most precious resource?
Water.
What is earths outer most physical layer divided into tectonic plates?
Earth's outermost physical layer is divided into tectonic plates known as the lithosphere. These plates float on the semi-fluid asthenosphere beneath them and are responsible for the movement of continents due to the process of plate tectonics.
What is most responsible for the pressure in the earths atmosphere?
The weight.
Which is thought to be most responsible for earths ice ages?
Earth's precession
Which force is most responsible for the earths revolution around the sun?
Gravity.
What leader was most responsible for unifying Europe during the early middle ages?
Charlemagne
Who was the most important king of the middle ages?
Charlemagne, king of the Franks. He is largely responsible for the initial shaping of Western Culture as we know it.
What group was most responsible for maintaining a level of literacy during the Dark Ages by focusing on learning Greek Latin and Hebrew?
Monks
What did Europeans of the Dark Ages make cloth from?
During the Dark Ages, or Early Middle Ages, most European cloth was either wool or linen. Cloth was also made from cotton and silk, though these were really only worn by wealthy people as for most Europeans they were imports.
When do most individuals start smoking?
Most people start smoking when they're in middle and high school. Near the ages 13 though 19.
Is a widow responsible for her deceased husband's debts even though there is no estate?
That is the reason to create an estate. However, in most cases the spouse will have benefited from the debt and be held responsible.
Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
What is the large area of Earth's surface covered with?
Most of the earths surface is covered with water. There is land under that water though, below the surface.
What season is it when the sun is heating earths surface the most?
It is summer when the sun is heating earths surface the most.
