Solar Radiation and Energy Questions

Multiple choice

Which gives you cause to worry in the hot summer sun?

  1. Gamma Rays

  2. IR Rays

  3. UV Rays

  4. Ray's Pizza
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ultraviolet (UV) rays from the sun are ionizing radiation that can damage skin cells and increase the risk of skin cancer. Gamma rays are not typically associated with sunlight exposure, and IR rays are primarily heat.

Multiple choice

Energy you can see is called:

  1. light energy

  2. electrical energy

  3. mechanical energy

  4. thermal energy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Light energy is the portion of the electromagnetic spectrum that is visible to the human eye. Other forms of energy like thermal or electrical are not directly visible as light.

Multiple choice

What is the source of most electromagnetic radiation on Earth?

  1. the Sun

  2. the moon

  3. light bulbs

  4. flashlights
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Sun emits a vast amount of electromagnetic radiation across the spectrum, which is the primary energy source for Earth. While bulbs and flashlights produce light, they are not the primary source for the planet.

Multiple choice

Which of the following sources does NOT give off ambient light?

  1. lamps

  2. candles

  3. the Sun

  4. a fire
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ambient light refers to the natural or existing light in a scene that is not provided by the photographer. The Sun is the primary source of natural light, whereas lamps, candles, and fires are considered artificial or supplemental light sources.

Multiple choice

What do solar panels use to operate?

  1. Electricity

  2. The suns thermal energy

  3. Water

  4. The suns UV light
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Photovoltaic cells in solar panels convert the energy from the sun's light (specifically UV and visible light) directly into electricity.

Multiple choice

Plants transform energy from the sun into:

  1. nulear energy

  2. chemical energy

  3. solar energy

  4. mechanical energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During photosynthesis, plants capture solar energy from the Sun and convert it into chemical energy stored in the chemical bonds of glucose molecules. This stored chemical energy can later be used by the plant or by consumers that eat the plant.

Multiple choice

In what process do plants use the Sun's energy to make food?

  1. photosynthesis

  2. transpiration

  3. germination

  4. cell respiration
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Plants use solar energy, carbon dioxide, and water to synthesize glucose (food) through photosynthesis. Transpiration is water loss, germination is seed sprouting, and cellular respiration breaks down glucose for energy.

Multiple choice

Which of the following is NOT a way that animals use energy from the Sun?

  1. for body and cell repair

  2. for growth

  3. for body warmth

  4. for smelling prey
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Smelling prey relies on chemical receptors (olfaction) and does not directly utilize energy derived from the Sun. In contrast, cellular repair, growth, and maintaining body warmth are biological processes powered by energy originally captured from the Sun.

Multiple choice

How does chicken contain energy from the Sun?

  1. chickens use sunlight to make food

  2. chickens walk around in sunlight

  3. chickens eat grains containing the Sun's energy

  4. chickens absorb sunlight during consumption
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chickens are consumers that feed on grains (producers) that have stored solar energy through photosynthesis. Thus, the energy in chicken meat ultimately originates from the Sun via the food they eat.
