What is humidity?
This was the teacher who tragically passed away in the Challenger disaster.

This zone receives no light, is the coldest, and has the highest pressure.
What is the Hadal (or trench) zone?
This is the layer of the atmosphere where the ISS orbits Earth; it is also the hottest layer.
What is the thermosphere?
These are caused by changes in air pressure.
What are winds?
This is an object that orbits something in space; it is used to collect data and for communication.
What is a satellite?

What is the umbra?
This is the flat, smooth ocean bottom.

What is the continental shelf?
Gases, such as methane, carbon dioxide, and water vapor, contribute to this global effect.
What is the greenhouse effect?
These are atmospheric areas with similar temperature and humidity.
What are air masses?
This tool is used to study space by reflecting or refracting light to magnify images and by receiving radio waves.
What is a telescope?
This moon phase happens after a full moon and before a 3rd quarter moon.
What is the waning gibbous phase?
This ocean zone makes up 80% of all oceans and covers 60% of Earth's surface.
What is the abyssal zone?
This is the coldest layer of the atmosphere and the least studied. It is also where meteors burn up.
What is the mesosphere?
This tool measures wind speed.
What is an anemometer?
This tool separates white light into various spectrums of color; it is used to help us study the stars.
What is a spectroscope?
This tide occurs during the new moon and full moon phases.
What is spring tide?
