The Dynamics of Space Weather and Its Impact on Earth

The video explains how the sun, though appearing constant from Earth, is actually active and turbulent. Space weather, caused by solar activity, can impact Earth's technological infrastructure. Solar storms, like the Carrington event, can disrupt power grids, communications, and GPS. NOAA and international partners use satellites to observe and forecast space weather, aiming to prepare for potential impacts. As space exploration and commerce grow, understanding space weather becomes increasingly important.

What is space weather primarily caused by?

• Earth's atmosphere

• The moon's gravitational pull

• Ocean currents

• Solar activity

What is the solar wind?

• A magnetic field around Earth

• A type of solar flare

• A stream of particles from the sun

• A type of terrestrial wind

What was the Carrington event?

• A volcanic eruption

• A major earthquake

• A large solar storm

• A hurricane

How can solar storms affect Earth?

• By cooling the planet
