Light
This natural source of light appears to rise in the morning.
What is the Sun?
This is the word for how hot or cold something is.
What is temperature?
This fluffy white thing in the sky brings rain or snow.
What is a cloud?
Volcanoes are often found at the edges of these giant Earth plates.
What are tectonic plates?
This part of the cell controls the activities of the cell and contains DNA.
What is the nucleus?
This is created when an object blocks light and creates a dark area behind it.
What is a shadow?
This tool measures temperature.
What is a thermometer?
When warm, moist air rises quickly, it can cause this violent storm with thunder and lightning.
What is a thunderstorm?
This hot, melted rock comes out of a volcano during an eruption.
What is lava?
This is an organism that is made of only one cell, such as bacteria.
What is a unicellular (single-celled) organism?
When light bounces off a smooth surface, this process occurs.
What is reflection?
This is the type of heat transfer that happens through direct contact.
What is conduction?
This spinning storm forms over warm ocean water and has very strong winds.
What is a hurricane?
This type of boundary happens when two tectonic plates move toward each other and collide.
What is a convergent boundary?
This part of the cell controls what enters and leaves the cell.
What is the cell membrane?
When light bends as it passes through water or glass, it's called this.
What is refraction?
This type of energy transfer happens through space, like how the Sun heats Earth.
What is radiation?
This type of storm can drop chunks of ice from the sky, even in warm weather.
What is a hailstorm?
This is the name for a type of plate boundary where plates slide past each other and earthquakes usually happen?
What is a transform boundary?
This organelle releases energy from food for the cell to use.
What is the mitochondrion?
When light passes through a clear material, like glass or water, it undergoes this process.
What is transmission?
When heat moves through liquids or gases (like boiling water), it's called this.
What is convection?
This part of the water cycle is where water vapor turns into liquid droplets that form clouds.
What is condensation?
This is the area where one tectonic plate slides beneath another, often causing volcanic activity.
What is a subduction zone?
During cellular respiration, this molecule is broken down in the mitochondria to release energy that cells can use for life processes.
What is glucose?
