What was earths climate during the Jurassic period like?
During the Jurassic period, Earth's climate was generally warmer and more humid than today. Polar regions were ice-free, and forests covered much of the land. Dinosaurs flourished in this lush environment.
Cold area where the sun's rays strike at a very low angle?
Polar regions such as the Arctic and Antarctica experience low-angle sun rays due to their high latitudes. This angle results in colder temperatures and long periods of darkness during winter. The low angle of the sun's radiation also contributes to the formation of sea ice and glaciers in these regions.
Where is the lowest risk of tornadoes?
The lowest risk of tornadoes is generally in regions located near the equator, such as the equatorial regions of Africa, Asia, and South America. These areas experience less tornado activity due to the lack of significant temperature variations and weather patterns conducive to tornado formation.
Why do marine organisms living in polar regions have a very high proportion of cholesterol in their membrane?
Marine organisms living in polar regions have a very high proportion of cholesterol in membranes to keep the membranes more fluid and keep the molecules moving faster because in cold temperature, molecules move slower.
How do polar and non-polar bonds interact with each other?
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.
Very long days or nights occur at the?
Near the polar regions.
What is the annual rainfall for the polar regions?
In the polar regions, the annual rainfall is very low due to the cold temperatures. Instead of rain, these regions primarily receive snowfall. Snowfall can vary depending on the specific location within the polar regions.
Explain how the salinity of water in polar regions very seasonally?
The salinity of water in polar regions varies seasonally because of the melting of sea ice during warmer months.
Why are reptiles rarely found in the polar regions?
There are no reptiles in the polar regions it is too cold for them as they are cold blooded.
Why do ice cores taken from polar regions contain much older information about Earth's climate than ice cores taken from mountaintops?
Because the snow is very compressed in the polar regions
Why do ice cores taken from polar regions contain much older information about earths climate than icecores taken from mountaintops?
Ice cores taken from polar regions provide a more continuous record of past climate changes due to the stable, low-temperature conditions that preserve layers of ice over long periods. In contrast, ice cores taken from mountaintops are more prone to melting and erosion, leading to a less reliable and shorter record of climate history. Additionally, polar regions receive more snowfall, which results in thicker ice sheets that can provide a deeper time perspective compared to mountaintop ice cores.
What are the fur bearing animal always found in the cold regions?
as the polar regions are very cold , the fur bearing animals like polar bear, squirrel, snow fox, polar wolves, reindeer etc are found the thick wool present on the body of these animals protect them from severe cold.
What would happen if some days are very long while some are very short?
That already happens in polar regions during summer and winter.
Do only penguins live in igloos?
Penguins do not live in igloos. Eskimos, who live at the north polar regions, live in igloos. Penguins live in the southern polar regions. There are very few people, and no igloos, at the south pole.
Why plants in polar regions have very short growing season?
Plants in polar regions have very short growing seasons due to extreme cold temperatures that inhibit plant growth. The presence of snow and ice for much of the year also makes it challenging for plants to grow and photosynthesize. Additionally, limited sunlight during the polar winter, known as polar night, further restricts the time available for plants to carry out photosynthesis and grow.
Where do tornadoes never occur?
Tornadoes can potentially form anywhere around the world, but they are most commonly observed in the central United States. However, there are some regions with very low occurrences of tornadoes, such as Antarctica and parts of the Arctic.
What are ways polar regions and desert regions different?
Polar regions are characterized by extreme cold temperatures, while desert regions are known for their extreme heat. Additionally, polar regions receive a lot of snow and ice, whereas deserts receive very little precipitation. The flora and fauna in each region are adapted to survive in their respective harsh environments.
