Responses
extra currents in the ground will disrupt power grid operations
extra currents in the ground will disrupt power grid operations
signals from radio navigation systems will be disrupted and be inaccurate
signals from radio navigation systems will be disrupted and be inaccurate
satellites will be forced to Earth's surface
satellites will be forced to Earth's surface
high-frequency radio waves used for radio communications will intensify
The correct answers are:
1. Extra currents in the ground will disrupt power grid operations.
2. Signals from radio navigation systems will be disrupted and be inaccurate.
The two correct answers are:
1. Geomagnetic storms: These are disturbances in Earth's magnetic field caused by solar weather, particularly when there are large solar flares or coronal mass ejections (CMEs) from the Sun. To find this answer, one can conduct a search using reliable sources such as scientific journals or websites focusing on space weather.
2. Auroras: Also known as the Northern Lights (aurora borealis) or Southern Lights (aurora australis), these beautiful light displays are a result of charged particles from the solar wind interacting with Earth's magnetic field. To find this answer, one can search for information about the causes of auroras in reliable sources such as space science websites or physics textbooks.
