Leaming Task No. 2. Read each question and answer choices carefully. Choose the letter which corresponds to your answer and
write it on your answer sheet.
1. During the day, the sun's rays are most intense at what time of the day?
A dus
B. dawn
C. noon
D. morning
2. All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the
electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, Infrared, radio waves, Xrays, and gamma
rays. Radiation is one way to transfer heat. Some of this heat lost to space due to
A reflection and scattering
B. minimal absorption of the nearby black hole
C.It's speed
D. gravitational force of the Sun
3. This refers to a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region.
D. season
A weather dynamics
C. climate
B. quarterization
4. As the solar radiation reaches the Earth, it will be absorbed, reflected, or scattered. With the presence of clouds, some of the
radiation is absorbed. What particular percentage do clouds absorbed?
C. 70%
D. 100%
B. 50%
A. 20 %
5. Here on Earth, we define our day based on the motion of the
D. galaxies
C. stars
B. Sun
A moon
Answers & Comments
Answer:
1. C. NOON
Time of day: UV rays are strongest in the middle of the day, between 10 am and 4 pm
2. A .reflection and scattering
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
3. D. season
A season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of Earth's orbit around the Sun and Earth's axial tilt relative to the ecliptic plane.
4. C. 70%
In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder.
5. B.Sun
The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night
