Weather and Climate
What is an example of weather.
Sunny days, rainy days, snowy days, blizzards.
What gases is air made out of.
Nitrogen and oxygen.
What is water made out of.
Hydrogen and oxygen.
What percent of the world's species live in tropical rain forest's
around 50%
What is an example of climate.
Sunny days melting ice at the North Pole over time. Hot weather causing droughts in dry places. etc.
Name examples of greenhouse gases.
What percentage of the Earth's surface is covered in water.
71%
What can NASA's satellites monitor?
What is the difference between weather and climate.
Weather is something temporary. Climate describes the weather conditions over a long period of time.
What causes air pollution.
Gases that are emitted from factories, cars, volcanoes and wildfires. Dust, pollen and mold spores cause air pollution as well.
What causes sea water to rise.
Melting glaciers and the expansion of water as it gets water causes sea levels to rise.
What can trees tell us about climate change.
The rings in a tree can tell us the age and the growing conditions of the tree.
What is perma frost.
Ground that remains frozen for over 2 years.
What is the greenhouse effect.
Process that occurs when gases in Earth's atmosphere trap the Sun's heat. This makes the Earth warmer and more comfortable to live in.
What is Ocean acidification
Ocean acidification is the change in the properties of ocean water that is harmful for animals in the ocean.
What does a dark rings and light ring in a tree's stump mean.
Dark rings mean that the tree grew in the late summer and fall while light rings mean it grew during spring and early summer.
What does sea level tell us about climate change.
The sea level rises when ice melts which tells us that Earth's climate is getting warmer.
Why is carbon important?
Carbon which is a greenhouse gas traps heat close to Earth. This helps Earth contain the heat it gets from the Sun so it doesn't all escape back into space. If it weren't for carbon, Earth would be frozen solid.
What is coral bleaching.
Coral bleaching is when the corals turn white and animals can't live in it because the temperature and pollution in the water and air upsets it.
Why does NASA care about food?
NASA satellites monitor soil, temperature air and climate. Understanding these things will help farmers grow the food we eat.
