Solar Phenomena Quiz

On April 8, 2024, a significant astronomical event will take place: a total solar eclipse. During a total solar eclipse, the Moon passes between the Earth and the Sun, completely covering the Sun and casting a shadow on parts of the Earth. This rare event will be visible across parts of North America, and many people are preparing to witness this spectacular phenomenon.

What significant event will occur on April 8, 2024?

• A lunar eclipse

• A total solar eclipse

• A meteor shower

• A comet passing by Earth

Article: The Sun's Corona

The corona is the sun's super-hot outer atmosphere. It extends millions of kilometers into space and is much hotter than the sun's surface. The corona is visible during a total solar eclipse as a white halo around the sun.

What is the corona of the sun?

• The sun's core

• The sun's surface

• The sun's super-hot outer atmosphere

• The sun's magnetic field

Read the following article and answer the question below:

Article: The corona is the outermost part of the Sun's atmosphere. It was first identified as a part of the Sun by the Spanish astronomer José Joaquín de Ferrer during a solar eclipse in 1809. Before this discovery, the corona was observed during eclipses but was not recognized as belonging to the Sun itself.

Who discovered that the corona was part of the sun?

• Albert Einstein

• Isaac Newton

• José Joaquín de Ferrer

• Galileo Galilei

Read the article below and answer the question that follows:

Article: During a solar eclipse in 1868, scientists observed a yellow spectral line in sunlight passing through the Sun's atmosphere. This line did not match any known element on Earth. The element responsible for this line was later named helium, after the Greek word for the Sun, 'Helios'. Helium was the first element to be discovered in space before being found on Earth.

What new element was discovered during a solar eclipse in 1868?

• Helium

• Hydrogen

• Oxygen

• Carbon

Article: The Parker Solar Probe is a NASA spacecraft launched to study the Sun. It is designed to fly closer to the Sun than any spacecraft before it, gathering data about the Sun’s outer atmosphere and solar winds. This mission will help scientists better understand how the Sun works and how it affects the solar system.

What is the Parker Solar Probe designed to do?

• Study the moon

• Fly closer to the sun than any spacecraft before it

• Explore Mars

• Measure Earth's magnetic field

The Solar Orbiter is a spacecraft launched by the European Space Agency (ESA) with the main goal of studying the Sun, especially its poles, and understanding how the Sun creates and controls the heliosphere. The mission aims to provide close-up observations of the Sun and its polar regions, which have never been seen before, to help scientists learn more about solar activity and its effects on the solar system.

What is the main purpose of the Solar Orbiter spacecraft?

• Study the sun's poles

• Explore the outer planets

• Monitor Earth's weather

• Search for extraterrestrial life

The sun produces energy through a process called nuclear fusion. In this process, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This is different from burning coal, nuclear fission, or simple chemical reactions.

What process does the sun use to make energy?

• Burning coal

• Nuclear fission

• Turning hydrogen into helium

• Chemical reactions

Read the article below and answer the question.

Article: Solar winds are streams of charged particles released from the upper atmosphere of the Sun, called the corona. These particles travel through space and can affect planets, including Earth.

What are solar winds?

• Streams of particles from the sun

• Strong winds on Earth

• Ocean currents

• Air currents in the atmosphere

About the Sun's Photosphere

The photosphere is the visible surface of the sun that emits the light we see from Earth. It is not the sun's core or its outermost layer, but rather the layer from which most of the sun's radiation escapes into space. The photosphere appears bright and is often referred to as the sun's 'surface,' even though the sun is made entirely of gas.

What is the photosphere of the sun?

• The sun's core

• The sun's bright surface

• The sun's magnetic field

• The sun's outer atmosphere

Read the article below and answer the question.

Article: The sun is a star at the center of our solar system. By studying the sun, scientists learn not only about our own planet but also about other stars in the universe. Understanding the sun helps us discover how stars work and how they affect planets around them.

Why is studying the sun important?

• It helps us understand the moon

• It helps us learn about our planet and other stars

• It helps us predict weather patterns

• It helps us find new planets
