World Phenomena
Tap any card to learn how it happens.
Weather is the state of the air on a given day; climate is the average weather of a place over 30+ years.
The endless movement of water between oceans, air and land.
A seasonal change in wind direction that brings heavy rain.
Huge spinning storms that form over warm oceans.
Giant electric sparks inside storm clouds.
An arc of colours formed when sunlight passes through raindrops.
A narrow, violently spinning column of air reaching from a storm cloud to the ground.
Gases in the air trap heat, keeping Earth warm — too much makes it overheat.
Earth spins on its axis once every 24 hours.
Seasons happen because Earth's axis is tilted 23.5°.
Sudden shaking of the ground caused by moving rock plates.
Openings in the crust where molten rock (magma) escapes.
Continents slowly move a few centimetres each year.
Glowing curtains of light in polar skies.
Rocks are broken down and carried away by water, wind and ice.
The daily rise and fall of sea level.
Giant sea waves caused by undersea earthquakes or eruptions.
Rivers of water flowing through the oceans.
Changes in Pacific Ocean temperature that affect weather worldwide.
When the Sun, Earth and Moon line up and cast shadows.
The Moon seems to change shape over about 29.5 days.
The force that pulls objects with mass toward each other.
Space rocks and icy visitors that light up the sky.
Places where gravity is so strong that not even light can escape.
Stars are born, shine for billions of years, and die.
The universe began about 13.8 billion years ago from an extremely hot, dense point and has been expanding ever since.
Galaxies are moving away from each other — space itself is stretching.
Invisible stuff that makes up 95% of the universe.
Huge families of billions of stars held together by gravity.
The distance light travels in one year — about 9.46 trillion km.
A cloud that forms at ground level.
Balls of ice falling from thunderstorm clouds.
A long period with much less rain than normal.
Water overflowing onto normally dry land.
Strong winds lifting huge clouds of sand and dust.
Frozen ice crystals falling from clouds.
Several days of unusually hot weather.
Rock and soil suddenly sliding down a slope.
Hot water shooting out of the ground.
Huge rivers of ice that move slowly downhill.
Underground chambers carved by water.
Underwater structures built by tiny animals called corals.
Spinning bodies of water.
Living things that glow in the dark.
Giant explosions and dark cool patches on the Sun.
The giant explosion of a dying star.
A ring of rocky pieces between Mars and Jupiter.
Icy bodies that grow glowing tails near the Sun.
Giant clouds of gas and dust where stars are born.
Imagined tunnels through space-time, predicted by Einstein's theory.
