What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself. Hot fluid rises, while cooler fluid sinks, creating a current.

Front

How does heat transfer occur when frying bacon?

Back

The stove burner transfers heat directly to the pan, and the pan directly transfers heat to the bacon.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the net force if all forces acting on an object cancel each other out?

Back

0 N (zero newtons) means there is no net force acting on the object.

Front

What is wind?

Back

Wind is the movement of air from areas of high pressure to areas of low pressure.

Front

What happens if Earth didn't have an atmosphere?

Back

We wouldn't be able to breathe, and life as we know it would not exist.

Front

What is weather?

Back

Weather refers to the day-to-day conditions of the atmosphere at a specific place, including heat, dryness, sunshine, wind, and rain.

Front

What is the difference between weather and climate?

Back

Weather is short-term atmospheric conditions, while climate is the long-term average of weather patterns over a significant period.

Front

What is the role of the atmosphere?

Back

The atmosphere protects life on Earth by providing oxygen, regulating temperature, and shielding from harmful solar radiation.

Front

What is pressure in the context of the atmosphere?

Back

Atmospheric pressure is the force exerted by the weight of air above a surface, affecting weather patterns and wind.
