Solar Wind and the Magnetosphere

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)
