Write a paper explaining what causes seasons as the season shifts from Winter to Spring at a place located 400 N of the equator.

1. Watch the video clips A and B that are linked to Module 5 as 5.3 Video Clips and write a summary of at least two sentences for each clip describing what you have learned from each clip. (2 pts) (You should list your sentences as A1, A2, and B1, B2. Please follow directions properly as you list your video clip sentences so that they can easily be identified by your classmates)

2. Explain what causes seasons. As the season shifts from Winter to Spring at a place located 400 N of the equator, (A) does the sun angle increase or decrease? (B) does the amount of solar radiation increase or decrease? (C) does the length of daylight increase or decrease? (2pts)

3. Where does the air temperature show more variation in the coastal area or inland locations? Why? (2pts). (Hint: consider the differences in specific heat capacity between water and land).

4. Define global warming, and discuss at least one cause, one effect, and one method of reducing global warming (2pts).

Introduction:

Seasons are periodic changes that occur in the Earth’s climate, characterized by changes in temperature, weather conditions, and the length of daylight hours. These changes are caused by various factors, including the tilt of the Earth’s axis, the position of the Earth in its orbit around the sun, and the amount of sunlight that reaches different parts of the Earth’s surface. In this paper, we will explore the causes of seasons as the season shifts from winter to spring at a place located 40°N of the equator.

The Tilt of the Earth’s Axis:

The tilt of the Earth’s axis is one of the primary causes of seasons. The Earth’s axis is tilted at an angle of 23.5 degrees relative to its orbit around the sun. As the Earth orbits the sun, different parts of the planet receive varying amounts of sunlight depending on their position in relation to the sun. During the winter months, the northern hemisphere is tilted away from the sun, and as a result, receives less sunlight than the southern hemisphere. This causes colder temperatures and shorter daylight hours in the northern hemisphere during winter.

As the Earth continues its orbit around the sun, the northern hemisphere gradually tilts back towards the sun, resulting in longer daylight hours and

warmer temperatures during the spring months. This transition from winter to spring is known as the vernal equinox, which occurs around March 20th in the northern hemisphere.

The Position of the Earth in its Orbit:

The position of the Earth in its orbit around the sun also plays a role in the changing seasons. The Earth’s orbit is elliptical, which means that the distance between the Earth and the sun varies throughout the year. However, this variation in distance is not significant enough to cause the seasons. Instead, the position of the Earth in its orbit affects the intensity of the sunlight that reaches different parts of the planet.

During the northern hemisphere winter, the Earth is at its closest point to the sun, but because the northern hemisphere is tilted away from the sun, it receives less intense sunlight than the southern hemisphere. In contrast, during the northern hemisphere summer, the Earth is at its furthest point from the sun, but because the northern hemisphere is tilted towards the sun, it receives more intense sunlight than the southern hemisphere.

The Amount of Sunlight that Reaches Different Parts of the Earth:

The amount of sunlight that reaches different parts of the Earth is another factor that contributes to the changing seasons. The amount of sunlight that reaches a particular location depends on its latitude, or its distance from the equator. Places near the equator receive more direct sunlight throughout the year, while places near the poles receive less direct sunlight.

As the Earth orbits the sun, the angle at which the sunlight hits the Earth’s surface changes, resulting in different amounts of sunlight reaching different latitudes. During the winter months, the northern hemisphere is tilted away from the sun, and as a result, the sunlight hits the northern hemisphere at a shallower angle, resulting in less intense sunlight and colder temperatures. As the northern hemisphere tilts towards the sun during the spring months, the sunlight hits the northern hemisphere at a steeper angle, resulting in more intense sunlight and warmer temperatures.

Conclusion:

In conclusion, the changing of the seasons from winter to spring at a place located 40°N of the equator is caused by the combination of the tilt of the Earth’s axis, the position of the Earth in its orbit around the sun, and the amount of sunlight that reaches different parts of the Earth. Understanding these factors can help us predict and prepare for the changing weather patterns that come with each season.
