Name _______________________________ Period ______

Weather and climate are the two major abiotic (nonliving) factors responsible for determining the major geographic ecosystems called biomes.

Search the web and give a definition of weather:
The state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc.

Search the web and give a definition of climate: the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years.

Climate is closely associated with the seasons, but do you know what causes the seasons? Log on to the website below.

After watching the video, describe what causes the earth’s seasons. Give examples of the earth’s position to the sun in December vs. June and compare the northern and southern hemispheres.
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can. Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun. This means that on this date, day and night have about the same length: 12 hours each, more or less.

    Approximately half of the Earth is illuminated at any time by the Sun. At the equator the daytime is almost twelve hour in length. This is because In the Northern Hemisphere, the length of the day is longer during the months when the North Pole is tilted towards the Sun and shorter during the months when it's tilted away from the Sun. The reverse is true for the Southern Hemisphere. The Equator is exactly halfway in between the poles. So it wouldn't make any sense for a day on the equator to be longer when one of the poles is tilted towards the Sun, and shorter when the other one…

    Ohio is warmer in the summer than in the winter because it is closer to the sun due to Earth rotating on a tilted axis while making revolutions around the sun. This axis that the Earth rotates on makes hemispheres of Earth closer or farther to the sun during a year, or revolution, that causes our seasons. For example in the beginning of the revolution, the Northwestern hemisphere is farthest from the sun, thus it is cold, giving us Winter. As we make our revolution around the sun, the Northwestern hemisphere becomes closer to the sun as the opposite (Southeastern) hemisphere moves away from the Sun, it becomes warmer, thus giving us summer. Since we are always making revolutions around the sun, the seasons will continue changing. This…

    Does Earth Have Seasons

    • 1653 Words
    • 7 Pages

    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 be opposite of what they are. In the Northern Hemisphere, the part of the year when the Earth is closer to the Sun, we are in winter. But the part of the year that it is farther away, we are in summer. How is this possible? The reason that seasons…

    Even if immediate action is taken, there would still be lasting implications on the entire planet. Things such as rising sea levels, health implications, and severe droughts could all happen because of an increase atmosphere temperature. While some areas would be subjected to scorching temperatures, other would be plunged underwater. Warmer climate would allow for a longer breeding season for microbes and parasites. Action to stop climate change needs to happen as soon as possible before it could get worse.…
