14 million degrees
20 million degrees
What is the name of the element created when hydrogen atoms are squeezed together in the Sun's core?
Nitrogen
Carbon
Helium
Oxygen
What is the name of the huge Eddie's in the outer layers of the Sun that move heat to the surface?
Convection cells
Magnetic fields
Sunspots
Plasma
What happens when the magnetic rubber band of the Sun breaks and gas from the solar storm streams along the magnetic lines towards the poles on the night side?
Daylight Aurora
Solar storm
Nighttime Aurora
Sunspots
What is the name of the invisible shield that deflects the solar storm when it reaches Earth?
Magnetic field
Plasma
Convection cells
Sunspots
State three structures of the Sun that form the Sun’s atmosphere.
radiation zone
Photosphere,
convection zone
chromosphere
corona
State three phenomena that occur on the surface of the Sun where charged gases erupt.
Prominence
coronal mass ejection
sunspot
solar flare
Define Earth’s magnetosphere.
Particles in plasma such as electrons, protons and alpha particles that erupt from the Sun to outer space travel together at high speeds
It is
a combination of the Earth's magnetic field (as the main magnetic field) and the magnetic field in the region in space.
spouts magnetic particles at high speeds into outer space and appears like an expanding cloud. These magnetic particles from the coronal mass ejection take three days to reach Earth.
huge loop
or arched column of glowing gases over the sunspot.
What influences the shape of the magnetosphere?
solar flare
prominiences
solar wind
solar cycle
geomagnetic storm
Name one object in the Solar System that has the same shape as solar wind.
asteroid
comet
meteroid
planet
What is the definition of space weather?
biological shield to protect life on Earth from the adverse effects of solar wind
interaction between the magnetic field brought by the solar wind and Earth’s magnetic field
Phenomena that occur on the surface of
the Sun and in outer space.
outer space surrounding Earth where the magnetic field in Earth’s magnetosphere is a combination of Earth’s magnetic field (as the prime magnetic field) and the magnetic field in the region in outer space
State four examples of the effects of space weather on Earth
Formation of aurora
disturbances to telecommunication
disturbances to navigation system
disturbances to electric power lines
What is the relationship between the number of sunspots and the increase in coronal mass ejections?
When the number of sunspots decrease,
coronal mass ejections will increase.
When the number of sunspots increases,
coronal mass ejections will increase.
When the number of sunspots increases,
coronal mass ejections will decrease.
the number of sunspot does not give effect to coronal mass ejection
What is the importance of earth magnetosphere
reduces the pressure exerted by solar wind on Earth’s atmosphere
functions as a biological shield to protect life on Earth from the adverse effects of solar wind
blocks charged particles such as electrons, protons and alpha particles in the solar wind from reaching Earth
seems to appear and disappear according to a cycle that lasts 11 years
choose equipment or service used daily which can be disrupted by solar winds.
Smartphone (mobile)
Internet
TV broadcast
Global positioning system (GPS)
