1.
What is the axis?
Correct Answer
D. The angle at which the earth is tilted to the position of the Sun.
Explanation
The axis refers to the angle at which the Earth is tilted to the position of the Sun. This tilt is responsible for the changing seasons and the varying lengths of daylight throughout the year. The axis is an imaginary line that passes through the North Pole and the South Pole, around which the Earth rotates. It is this tilt that causes different parts of the Earth to receive varying amounts of sunlight, resulting in the different seasons experienced in different hemispheres.
2.
At the winter solstice, which part of the Earth has 0 hours of daylight?
Correct Answer
B. North pole
Explanation
The winter solstice occurs when the North Pole is tilted furthest away from the sun, resulting in the shortest day and longest night of the year in the Northern Hemisphere. At this time, the North Pole experiences 0 hours of daylight because it is constantly in shadow due to the Earth's tilt. Therefore, the correct answer is the north pole.
3.
From your observation of the Earth as it moved around the Sun, you would have noticed that:
Correct Answer
B. Not all places on Earth have equal hours of daylight and darkness.
Explanation
From your observation of the Earth as it moved around the Sun, you would have noticed that not all places on Earth have equal hours of daylight and darkness. This is due to the tilt of the Earth's axis, which causes different regions to receive varying amounts of sunlight throughout the year. As the Earth orbits the Sun, the tilt causes the angle at which sunlight hits different parts of the Earth to change, resulting in the changing lengths of daylight and darkness.
4.
Countries at different positions on Earth have different time because of the ___________
Correct Answer
Earth's rotation.
Explanation
The reason why countries at different positions on Earth have different times is because of the Earth's rotation. As the Earth rotates on its axis, different parts of the planet experience daylight and darkness at different times, leading to the concept of time zones. This allows for standardization of time across different regions and helps coordinate activities and schedules globally.
5.
To complete one rotation the Earth's takes _____________ hours.
Correct Answer
24
Explanation
The Earth takes 24 hours to complete one rotation. This is because the Earth rotates on its axis, which is an imaginary line passing through the North and South Poles. It takes approximately 24 hours for the Earth to make a full rotation, resulting in day and night cycles. This period of rotation is known as a day and is divided into 24 hours.
6.
Therefore to make a complete spin, that is ___________ degrees the Earth takes 24 hours.
Correct Answer
360
Explanation
The Earth takes 24 hours to complete a full rotation of 360 degrees. This means that in one day, the Earth completes a full spin, returning to its original position. Therefore, to make a complete spin, the Earth needs to rotate 360 degrees.
7.
So when we calculate, that is, 360 degrees divided by 24 hours, the answer we get is in 1 hour the earth rotates through ________ degrees.
Correct Answer
15
Explanation
When we calculate the rotation of the earth, we divide 360 degrees by 24 hours to determine how many degrees the earth rotates in one hour. Therefore, the correct answer is 15 degrees.
8.
The starting point of reference to calculate time will be the 0 degree longitude which passes through ______________ ,near London. It is known as the Prime Meridian.
Correct Answer
Greenwich.
Explanation
The starting point of reference to calculate time is the Prime Meridian, which passes through Greenwich, near London. This is commonly known as Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC). The choice of Greenwich as the reference point for time calculation is based on historical reasons and the establishment of the Royal Observatory in Greenwich in the 19th century, which played a significant role in the development of accurate timekeeping and navigation.
9.
So, a place 15 degree to the east of the Prime Meridian will be 1-hour _________ than Greenwich.
Correct Answer
later
Explanation
A place 15 degrees to the east of the Prime Meridian will be 1-hour later than Greenwich. This is because the Earth rotates 360 degrees in 24 hours, meaning that each hour corresponds to 15 degrees of longitude. Therefore, for every 15 degrees to the east of the Prime Meridian, the time is 1 hour later.
