Lab 06 – Why We Have Seasons
Question 1:
The table below contains entries for the coordinates for the sun on the
ecliptic as well as the latitude at which the most direct and least direct rays of the sun
are hitting. Use the simulation to complete the table.

Question 2:
Using the data in the table above, formulate general rules relating the
declination of the sun to the latitude where the most direct and least direct rays of the
sun are hitting.
Answer
:
Wit this we can tell that the declination of the sun is almost equal to the
Latitude of most direct ray. If it is negative then that means that it would be a latitude
that is south of the equator.
Question 3:
The region between the Tropic of Cancer and the Tropic of Capricorn is
commonly known as the tropics. Using the sunlight data table from question 1, define
the significance of this region.
Answer
: This area gets a lot of direct sunlight exposure which leads to higher
temperatures than the rest of the world.
Question 4:
Using the sunlight data table from question 1, define the significance of the
region north of the Arctic Circle commonly referred to simply as the Arctic.
Answer
:
This area receives the least amount of direct sunlight according to the chart.
This could be a factor to the very cold temperatures experienced there.
Question 5:
Use the simulator to complete the table below.
For each latitude, write a
short paragraph which describes the variations in sunlight (seasons) that are
experienced at this latitude throughout the year.
Latitude
Description of Yearly Pattern of Sunlight
0°
The noon sun’s angular height above the horizon ranges from 90° on
the vernal equinox, to 66.5° on the summer solstice, to 90° on the
autumnal equinox, and back to 66.5° on the winter solstice. Thus, the
equator always receives very direct intense sunlight throughout the
year which accounts for the very high temperatures.
23.5° N
At noon the suns height is from 66* 30’00 on the vernal equinox to 90* on the
summer solstice, to 66* on the autumnal equinox and to 43 on the winter
solstice. This area gets a lot of direct sunlight as it is near the equator.
41° N
The height of the sun at noon above the horizon ranges from 49* to 72*. This
region is very temperate and receives a fair amount of sunlight.
66.5° N
This has the sun at an angular height above the horizon with ranges from 23*
to 47* during the vernal equinox. During the summer solstice to 23* and on
the autumnal equinox and to 0 on the winter solstice. They get less sunlight
than normal and the day is usually less than the night throughout the year.
90° N
The noon’s height ranges from 0 on the vernal Equinix to 23* on the summer
solstice. On the winter solstice the sun is below the horizon. This is the north
pole and it is very cold as tit receive the least amount of sunlight.
