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.
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.
He called this movement a continental drift. Wegener was convinced that all of Earth's continents were once part of an enormous, single landmass called Pangaea. Wegener, trained as an astronomer, used biology, botany, and geology to describe Pangaea and continental drift.
A conditioned stimulus is the one which was previously a neutral stimulus but hen it gets paired with the unconditioned stimulus it leads to a conditioned response.
The learned response which is produced in response to a neutral stimulus is the conditioned response.
In the given condition the smell or taste of a chicken salad causes Allison to feel nauseated and hence, the taste or smell of a chicken salad is the conditioned stimulus which generates a conditioned response which in this case is nausea.
If ice were more dense than water, it would freeze and sink over and over until the entire lake was frozen. ... This same process occurs in the fall as the surface water cools and becomes more dense; it will sink and cause the same movement or turnover of the lake's water.
the more people the less water, we can use water to clean our selves or to water our plants or pets, we throw trash in to the water and pollute our water resources
