#1
What is the main source of energy for the Earth's climate system?
Solar radiation
ExplanationSolar radiation powers the Earth's climate system by providing heat and energy.
#2
Which of the following is not a solar phenomenon?
Tornadoes
ExplanationTornadoes are not related to solar phenomena; they are atmospheric phenomena on Earth.
#3
What is the primary source of energy for the Earth's climate system?
Solar energy
ExplanationSolar energy is the primary source of energy for the Earth's climate system, driving weather patterns and sustaining life.
#4
What is the Sun mainly composed of?
Hydrogen and helium
ExplanationThe Sun is primarily composed of hydrogen and helium, with trace amounts of other elements.
#5
What is the solar cycle?
The approximately 11-year cycle of sunspot activity on the Sun
ExplanationThe solar cycle is an 11-year cycle of varying solar activity, including changes in sunspot numbers and solar radiation.
#6
What is the approximate surface temperature of the Sun?
15000 degrees Celsius
ExplanationThe Sun's surface temperature is approximately 15000 degrees Celsius.
#7
What causes the phenomenon known as the solar wind?
High-speed particles ejected from the Sun's corona
ExplanationThe solar wind is formed by high-speed particles ejected from the Sun's corona.
#8
What is the name of the process by which the Sun produces energy?
Nuclear fusion
ExplanationThe Sun produces energy through the process of nuclear fusion, where hydrogen atoms fuse to form helium, releasing energy in the process.
#9
Which layer of the Sun's atmosphere is the hottest?
Corona
ExplanationThe corona is the outermost layer of the Sun's atmosphere and is hotter than the Sun's surface.
#10
Which phenomenon causes the Northern Lights (Aurora Borealis)?
Solar flares
ExplanationSolar flares are responsible for the Northern Lights, creating colorful displays in the polar regions.
#11
What is the solar constant?
The amount of solar energy received at the Earth's surface per unit area per unit time
ExplanationThe solar constant is the quantity of solar energy reaching the Earth's surface per unit area and time.
#12
What is a solar flare?
A burst of energy from the Sun's surface
ExplanationA solar flare is a sudden and intense burst of energy and radiation from the Sun's surface.
#13
What is the solar wind?
A stream of charged particles from the Sun
ExplanationThe solar wind is a continuous stream of charged particles, including protons and electrons, flowing from the Sun into space.
#14
What is a solar prominence?
A loop of plasma that extends from the Sun's surface into the corona
ExplanationA solar prominence is a loop of plasma extending from the Sun's surface into the corona, often visible during solar events.
#15
How does the Sun's magnetic field affect Earth?
It creates the Northern and Southern Lights
ExplanationThe Sun's magnetic field interacts with Earth's magnetic field, leading to the phenomenon of the Northern and Southern Lights.
