space test study Flashcards
Age of the earth
3.5-3.8 billion year old i think
how does the distance from the sun affect our atmosphere
Being in the habitable zone allows for the presence of water, possibly in different states (solid, liquid and gas) to cycle throughout an atmosphere.
The average temperature on earth
14-degree celcius
how the solar system formed
It was a gas cloud that got affected by a large supernova, this jump started our solar system and created our home star the sun, the rest of the gas formed into asteroids which collided into each other to form planets
how does the size of the planet affect our atmosphere
Small planets do not have enough gravity to “hold on”to small gaseous elements and compounds.
Large planets like Jupiter & Saturn have immensely thick atmospheres because their gravity can “hold on” even the smallest/lightest elements and compounds.
I FINK MABE WHAAAATT!
how does geological activity affect our atmosphere
Processes such as volcanism release the gases that become the components of a planet’s atmosphere.
orbital radius
The distance a planet orbits from its star is called an orbital radius.
what is Orbital Eccentricity aand why is it important
its the path of our planet in orbit, so like basically we go round and round like the merrygoround and if we go not round and like oval we would die because no habitable zone!! 😭
supernova
a supernova is the result of a dying star exploding
habitable zone
When a planet is positioned at a distance where liquid water can exist on its surface, it is considered to lay in the habitable zone of that star.
space weather
Space weather refers to changes in the space
environment and geomagnetic storms resulting from
eruptions on the Sun. Space weather ultimately affects
human activities and technologies on Earth and in space.
Solar Flares
is an intense burst of radiation coming from the
release of magnetic energy.
Coronal mass ejection (CME)
is a large explosion that hurls
superheated plasma (electrified gas) into interplanetary space.
Coronal holes
release high-speed streams of plasma that boost the solar wind.
