Sun Exam

What is the most abudant element in our Solar System?

• Hydrogen
• Iron
• Silicon
• Carbon

Every 11 years, the Sun has a solar minimum. This means

• Solar minimum is a period of least solar activity in the 11 year solar cycle of the sun.
• There are so many sunspots we can't count them.
• Temperatures decrease on Earth, causing well known weather patterns
• Eggs will balance and brooms will stand.

The sunspot cycle lasts

• 8 minutes
• 11 years
• 25 hours
• 440 years

Which of the following describes the Chromosphere?

• An orange red layer of atmosphere of the sun. Its thousands of miles thick.
• The uppermost part of the atmosphere of the sun. Its millions of miles thick.
• Lowest layer of the sun's atmosphere that is also its visible surface, has an average temperature of 5800K, and is about 400km thick.
• The backside of the sun.

Which of the following best describes a sunspot?

• a badge that records exposure to radiation
• star in our solar system, made of hydrogen and helium
• A stream of electrically charged particles that emanate from the sun's corona. This causes auroras and takes about 24 hours to arrive from the sun.
• a dark spot on the sun, which is cool by contrast to the surrounding photosphere

The convection zone is

• the blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon
• Protective layer in atmosphere that shields earth from UV radiation.
• the heat from the core rises to the top of this zone while cool areas sink
• where nuclear fusion occurs

The colorful, glowing display in the sky caused when particles from the sun strike oxygen and nitrogen atoms in the ionosphere; also called the Northern Lights

• American Bazinga
• Aurora Borealis
• Ausmus Beavismus
• Authoral Balust

The sun is composed of which two primary elements?

• Iron and Oxygen
• Carbon and Nitrogen
• Hydrogen and Helium
• Lithium and Boron

Which of the following describes the Parker Solar Probe?

• The Parker Solar Probe is a NASA robotic spacecraft launched in 2018 that is currently in solar orbit to probe the outer corona
• Lowest layer of the sun's atmosphere that is also its visible surface, has an average temperature of 5800K, and is about 400km thick.
• a badge that records exposure to radiation
• a colorful, glowing display in the sky caused when particles from the sun strike oxygen and nitrogen atoms in the ionosphere; also called the Northern Lights

A stream of electrically charged particles that emanate from the sun's corona. This causes auroras and takes about 24 hours to arrive from the sun.

• Radial Exposure
• Solar Wind
• 1st degree radiation
• Aurora
