What is thought to have caused the ice age

Biology

Nostrana [21]4 years ago

Answer:

It is believed that the ice age was caused by fluctuations in the amount of solar energy received by the planet in some periods of time.

Explanation:

Ice age is the name given to the period when thick layers of ice cover large areas of the Earth. These periods can last for thousands of years and dramatically change the characteristics of the planet. There have been some very significant ice ages in the history of the planet. At the end of the 19th century, much research showed that there were several ice ages, alternating with interglacial periods. The interglacial period or interglacial phase is characterized by warmer average temperatures and consequent thawing of the glaciers, while the ice ages are periods of very cold, where the temperature of the Earth is very low causing the increase of the glaciers. It is believed that the ice age was caused by fluctuations in the amount of solar energy received by the planet in some periods of time.

Answer:

Ice Age Explanation. Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth's climate during the Quaternary. In other words, variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.

How does the release of energy and nutrients from digestion help the rest of the body's systems?
olasank [31]

Answer:

Explanation:

The main goal of metabolism is for the ultimate release of energy. Energy is simply a function of the ability to do work. In this context, we consider energy in one of it forms, chemical energy.

The chemical energy obtained through digestion of food mostly in the form of glucose is the fuel for almost all of life's processes. This chemical form of energy serves as the power house for our functioning.

Energy is required by the brain to power it and carry out its function. Without energy being supplied to the brain, there won't be a living being.

Energy is needed for locomotion and other life activities. The muscles, bones and other appendages gets their coordination power from the energy released during metabolic processes.

It can be said that all life activities revolves round how organisms obtains and utilize energy.

Nutrients are the nourishment we derive from feeding. The nutrients helps to build our body parts e.g proteins. Energy are derieved from carbohydrates. Fats and oil are also energy sources and they help life functions. Vitamins and minerals supplies needed materials to make everyday life activities successful.

Most metamorphic processes take place
natka813 [3]

Most metamorphic processes take place B. a few kilometers below Earth’s surface.

<h3>Further explanation </h3>

Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs  locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.

There are other ways that metamorphic rocks can form,  Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.

Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.
