Total questions: 13
Worksheet time: 8mins
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)
What would happen to the condition of Earth if there is no magnetosphere?
Formation of aurora
all living would die because exposed to UV ray
all living would die because exposed to solar wind radiation higher than safe level
people experience sunburn
What is the duration of one solar cycle?
9 years
10 years
11 years
12 yeard
State the phenomenon related to solar cycle.
prominence
solar flare
solar wind
solar cycle
