Snowball earth is when the Earth was covered by ice and snow from pole to pole for long periods of time in the past. The average temperature on the surface was about -50° and at the equator it was about -20°‚ which is roughly the temperature of Antarctica today. This is because the solar radiation from the Sun is reflected back into space due to the icy surface of the Earth. The oceans play a major role on the temperature fluctuation associated with day and night and because the oceans have a layer

Identify which block (A or B) modelled the surface of the Earth in: a. Far north Queensland - B b. Southern Tasmania – A 3. Use your results to explain why: a. The tropics are found near the equator The tropics are near the equator because the sun strikes earth at the equator due to the earth’s axis. b. Icebergs are only found in the poles Icebergs are only found in the poles because the tilt of the earth causes the sun not to shine at the poles and it is extremely cold at

1) Why does the Earth have seasons? Describe the relationship of the Earth and Sun in each of our four seasons. Contrary to what most people believe‚ seasons on Earth are not caused by the distance of our planet in relation to the Sun. This is a common misconception due to the Earth’s elliptical orbit around the Sun‚ which means there are times that the Earth is closer to the Sun‚ and times when it is farther away. If the Earth’s proximity to the Sun was the cause of our seasons‚ then they would

Equatorial The equatorial‚ hot‚ wet‚ climate is found between 5 degrees north and 10 degrees south of the equator. The temperature of the equatorial regions is hot throughout the year‚ with a very low temperature range usually of less than 3 degrees Celsius. Due to the heat in the equatorial belt mornings are bright and sunny. This causes evaporation and conventional air currents are set up‚ followed by heavy down pours of convectional rain. The amount of rainfall recorded in one afternoon may

been traveling to different part of the world‚ and the most spatacular place that caught my attention was the tropical rain forest.Tropical rainforests cover about 6% of the Earth’s total land surface. They are mainly located around the belt at the equator. The climate of the rainforest is warm most of the year and has a lot of rain through most of the year. The climate is perfect for animals and plant growth. Even though the rainforests cover such a little amount of land mass of the Earth‚ they are

incredibly large number of these species they produce around 50% of the world’s oxygen. Also some land animals are dependent on the sea as drinking and fishing grounds. Occasionally around the Equator an ‘El Nino’ happens. Usually this is caused by strong winds moving from East to West along the Equator. This actually piles up water in the western side of the Pacific. In the eastern part the deeper water‚ which is far colder than that on the surface (which is warmed by

begins to disintegrate. The centrioles in animal cells‚ fungi‚ algae and some other ferns double and a pair move toward each pole and the chromosomes begin to move toward the equator of the cell. The second stage is called the metaphase. In this stage the centrioles move to the poles. The chromosomes line up at the equator of the spindle and the spindle fibers are attached to the centromeres connecting them to the poles of the spindle. The third stage is called the anaphase. By this time‚ the
