Student Exploration: Seasons: Why do we have them?
Vocabulary: direct sunlight, Earth’s axis, equator, indirect sunlight, northern hemisphere, North Pole, season, solstice, southern hemisphere, South Pole, summer solstice, winter solstice
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. At what time of day is sunlight strongest – in the early morning (when the Sun has just risen) or at noon (when the Sun reaches its highest point)? At noon when the Sun reaches its highest point.
2. At what time of year does the noon Sun rise highest in the sky? During the summer time.
3. Based on your answers, why is it warmer in summer than in winter? It is warmer in the summer then in the winter because the Earth’s tilt is

B. Which of plates A through G will receive the least? Plates A and G will both receive the least amount of energy because the Sun’s rays will not hit those plates as directly as the rest.
2. Check: Click Fire. Select the TABLE tab to see how many rays hit each plate.
A. Which plate got the most sunlight? Plate D. The least? A and G.
B. Why is it colder at the poles than at the equator? The reason why is because the Sun’s rays hit those areas with the least amount of rays. They are also faced away from the sun the most compared the other areas meaning they will get the least of the Sun’s rays.
3. Set up Gizmo: Click Reset, and turn on Show axis. Earth’s axis is an imaginary line that connects the North Pole to the South Pole. Earth spins around its axis, which is tilted relative to Earth’s orbit. Click Earth axis angle to set the axis angle to a realistic 23°.
4. Collect data: On the DESCRIPTION pane, check that Time A is selected. Click Fire. Select the TABLE pane to see the results, and fill in the left table below. Click Reset, and on the DESCRIPTION pane select Time A + 6 months. Click Fire and fill in the right table.

5. Analyze: Plates A, B, and C all lie in the northern hemisphere, the half of Earth north of the equator. Plates E, F, and G all lie in the southern hemisphere,
Answer. I mentioned in question 2(b) that parts of Brazil because of the location near and right on the equator and the reason being is because twice in a year the sun's rays are vertical at the equator. Thus, the temperature is uniformly high in the equatorial region, and the annual range of temperature is negligible. (Rajan, 2012). The equatorial region experience so little winter cooling because of this. (Hess, 2011).
There are three main sections to this module: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic is related to seasons on the Earth. Each of these sections has its own simulator(s). The background material necessary to utilize these tools is contained in each section.

1: Describe the relationship between the UV Index (the colored bar in Figure 1) and latitude (y-axis).
10. North (in the Northern Hemisphere) South (in the Southern Hemisphere) – In the Northern Hemisphere the element of earth is linked to the north because the farther you travel north the longer the periods of darkness become. It is also true that the farther you travel north the colder the climates become. Therefore, traditionally the north has been associated the element of earth. These associations are reversed if you live in the Southern Hemisphere since traveling south will produce greater periods of darkness and
The data amassed by the scientist revealed that the Mid- Atlantic Ridge and the East Pacific Rise and countless other locations on the ocean floors display the same arrangements of varying magnetic stripes. As new volcanic rock erupts through fractures on the floor of the ocean, a progression identified as seafloor spreading, which causes the seafloor to widen (Trefil & Hazen, 2010). This new rock will be pushed aside as the continents are moved apart and as more magma comes up to take its place. The iron ore in this latest rock will steer to the position of the magnetic north pole once they get through to the top. Every occasion, that the planet’s magnetic field moves in the opposing direction, the dipole course of the planets magnetic field adjust and becomes encased in the recently constructed rock (Trefil & Hazen, 2010).
3. Does increased exposure to the sun’s light produce more current? Explain how you know this based on your data.
b) i): equal to about 1. The sun shines all year round, including the summer. Even though you may not be able to see the sun cause it’s hidden behind clouds it’s still shining.
B) Regions such as Labrador are actually colder than England because colder arctic air is pulled down to eastern North America and not to England.
A.The green flash, which is a light green color on the upper rim of the Sun as it is setting
Though Ayman understands that earth continues to spin he still does not have the knowledge the earth is continually spinning on its axis.
This image below shows which direction the North American plates and the Caribbean plates are moving
21. What is the correlation between temperature increase and global catastrophes? List four types of catastrophes related to temperature, and discuss the role temperature plays (some obvious of course!).
Latitude and longitude affect where people live because of many different reasons. One reason is the temperature. If you like warm weather, rainforest environments, and rainy seasons, this is the area for you. You will be able to find the equator at 0 degrees. If they like cold weather, they would move near the North Pole, which is ninety degrees north, or the South Pole, which is ninety degrees south.“ I’m crossed with longitude and latitude- Alice Cooper( Scarlet and Sheba)” (2016).
