Stars
Red giant
What does a low mass star become after it runs out of hydrogen in its core (leaves the main sequence stage)?
carbon dioxide
What is Mars atmosphere mostly composed of?
A strategy used to reduce the impact of climate change
What is an adaptation strategy?
Approximately 13.8 billion years old
How old is the universe?
Nebula
What is the first stage of a star
It's thin atmosphere
What makes Mars so cold at night time?
A process where greenhouse gases trap heat radiated from the Earth's surface, keeping the planet warm enough to sustain life
What is the natural greenhouse effect?
The amount of Red-shift increases
How does red-shift change when looking at planets that are further away?
Lack of sunlight and poor soil
Why is it so hard to grow crops on Mars?
The increased warming of Earth's atmosphere caused by human activities that release excessive greenhouse gases
What is the enhanced greenhouse effect?
Red-shift and cosmic microwave background radiation
What evidence is there to support the big bang theory?
Black hole or Nuetron star
What happens after supernova
Your bodily fluids would boil and you would freeze due to the low atmospheric pressure. Oh you'd also suffocate!
What would happen if you didn't wear a space suit on Mars?
Short term data can fluctuate from year to year from natural factors while using long term data shows consistent trends that can be used to see how climate is changing overtime
Why do scientists use long term data to study climate change?
100 to 500 million years ago
When did the first stars form?
A low mass star that has exhausted all its fuel and no longer emits any light
What is a black dwarf
Frozen at the poles or underground
Where is most of the water on Mars found?
Scientists drill deep into polar ice sheets to analyse trapped air bubbles, which reveal past levels of gases like carbon dioxide and show how today’s levels compare to the past.
What is ice core data?
You'd still expect the heat released during the big bang to exist in a cooler form. It's temperature fluctuations are also consistent with where stars and galaxies have formed
How does microwave background radiation support the big bang theory?
