"Solar Weather, insolation, solar output, sunspots, solar maximum and solar minimums"
"Daily and annual maximum and minimum temperatures."

• 1.

### Albedo - What is it?

• A.

The fraction of energy that is reflected back to space from something.

• B.

The amount of long and shortwave radiation in an area.

• C.

The balancing of long and shortwave radiation in an area.

• D.

The balancing of energy that is in an area.

A. The fraction of energy that is reflected back to space from something.
Explanation
Albedo refers to the fraction of energy that is reflected back to space from something. It is a measure of how much of the incoming solar radiation is reflected by a surface. A high albedo means that a surface reflects a large amount of energy, while a low albedo means that a surface absorbs more energy. This concept is important in understanding the Earth's energy balance and its impact on climate.

### What is a good example of a low albedo thing here?

• A.

Sand

• B.

Snow

• C.

Rain forest

• D.

High clouds

C. Rain forest
Explanation
A rainforest is a good example of a low albedo thing because it has a high absorption rate of sunlight. The dense vegetation and dark-colored surfaces in a rainforest absorb a significant amount of solar radiation, resulting in a low albedo. This means that a rainforest reflects very little sunlight back into space and instead absorbs most of it, contributing to higher temperatures in the region.

### What would be a good high albedo thing?

• A.

Forest

• B.

Ice

• C.

Freshwater

• D.

Ocean

B. Ice
Explanation
Ice has a high albedo because it reflects a large amount of sunlight back into space. This is due to its bright and reflective surface. Albedo is a measure of how much light an object or surface reflects, with a higher albedo indicating more reflection. Forests, freshwater, and oceans have lower albedo values as they absorb more sunlight rather than reflecting it.

### What is the daisy world model?b

• A.

The Daisy World Model is a model of a fictional world of several continents containing black and white daisies that reflect short and long wave radiation.

• B.

It is an area in Canada that has been planted in several areas with black and white daises, and then they use equipment to detect the short/longwave radiation

• C.

Its a 3d 'globe' model that displays white daisies that display what happens with long and short wave radiation.

• D.

Its an idea made up by a certain scientist of what the world would look like if half of it was covered with white daisies, the other half black daises, and what would happen with short and long wave radiation.

A. The Daisy World Model is a model of a fictional world of several continents containing black and white daisies that reflect short and long wave radiation.
Explanation
The Daisy World Model is a hypothetical model that simulates a fictional world with multiple continents, each populated with black and white daisies. These daisies have the ability to reflect short and long wave radiation. The model aims to study the effects of these daisies on the planet's temperature regulation and climate. It helps in understanding the concept of feedback loops and how the presence of daisies can influence the overall climate of the world.

### Space weather is the concept of changing environmental conditions in near-Earth space

• A.

True

• B.

False

A. True
Explanation
Space weather refers to the changing environmental conditions in near-Earth space. This includes variations in the magnetic field, radiation levels, solar wind, and other factors that can affect satellites, communication systems, and power grids. Therefore, the statement "Space weather is the concept of changing environmental conditions in near-Earth space" is true.

Rate this question:

• 6.

### A sunspot is a black spot on the sun that is extremely hot, hotter than the sun itself.

• A.

True

• B.

False

B. False
Explanation
Sunspots are cooler than the sun

Rate this question:

• 7.

### Solar maximum is when the greatest solar activity happens in space.

• A.

True

• B.

False

A. True
Explanation
Solar maximum refers to the period of time in the solar cycle when the sun's activity reaches its peak. During this phase, the sun experiences the highest number of sunspots, solar flares, and other solar phenomena. These events can have various effects on Earth, including disruptions to satellite communications and power grids. Therefore, the statement that solar maximum is when the greatest solar activity happens in space is true.

Rate this question:

• 8.

### Solar wind occurs when solar maximums occur.

• A.

True

• B.

False

B. False
Explanation
Its actually Sunspots.

Rate this question:

• 9.

### Solar minimum is when the least solar activity occurs.

• A.

True

• B.

False

A. True
Explanation
Solar minimum refers to a period of low solar activity characterized by a decrease in the number of sunspots, solar flares, and other solar phenomena. During this phase, the sun's magnetic field weakens, resulting in reduced solar activity. Therefore, it is correct to say that solar minimum is when the least solar activity occurs.

Rate this question:

• 10.

### In a solar minimum, sunspot and solar flare activity diminishes.

• A.

True

• B.

False

A. True
Explanation
During a solar minimum, the sun experiences a decrease in sunspot and solar flare activity. This is because solar minimum is a period of low solar activity, characterized by a decrease in the number and intensity of sunspots and solar flares. Sunspots are dark, cooler areas on the sun's surface that are associated with strong magnetic activity, while solar flares are sudden eruptions of energy from the sun. Therefore, it is true that during a solar minimum, sunspot and solar flare activity diminishes.

Rate this question:

• 11.

### Solar Minimum temperatures / Solar Maximum Temperatures

• A.

Cold / cold

• B.

Warm / warm

• C.

Cold / warm

• D.

Warm / cold

C. Cold / warm
Explanation
During a Solar Minimum, the Sun's activity decreases and there are fewer sunspots. This results in a decrease in solar radiation reaching the Earth, leading to cooler temperatures. On the other hand, during a Solar Maximum, the Sun's activity increases and there are more sunspots. This increases the amount of solar radiation reaching the Earth, causing warmer temperatures. Therefore, the correct answer is "cold / warm".
