The Higher, The Colder
The higher, the colder teaches Grade 5 students the counterintuitive atmospheric pattern: despite being closer to the Sun at high altitudes, air temperature decreases as altitude increases. This principle of atmospheric lapse rate explains why mountains have snow on their peaks even when it is hot at sea level below. The concept of altitude — height above the ground — is introduced as a key variable in understanding weather and cloud formation. This lesson is from Amplify Science (California) Grade 5, Chapter 3.
Key Concepts
You might think that getting closer to the sun would make the air warmer, but in our atmosphere, the opposite is true. As you go up, it gets colder.
We call the height above the ground altitude . There is a predictable pattern: as altitude increases, air temperature decreases. This is why tall mountains have snow on their peaks even when it is hot at the beach below.
Common Questions
Why does it get colder as you go higher in the atmosphere?
The atmosphere is heated mostly by Earth's surface, not directly by the Sun. Higher altitudes are farther from the warm surface and have thinner air that retains less heat, making them colder.
What is altitude?
Altitude is the height of something above the ground or sea level. It is measured in meters or feet and is used to describe the elevation of mountains, aircraft, or atmospheric layers.
Why do tall mountains have snow even when it is hot at the beach?
Temperature decreases with altitude. A mountain's peak may be thousands of meters above sea level where it is cold enough to keep snow year-round, even when low-elevation areas are warm.
How does temperature change with altitude affect cloud formation?
When moist air rises to colder altitudes, it reaches a point where water vapor condenses into droplets, forming clouds. The altitude at which this happens depends on how cold the air needs to get.
Does it always get colder as you go higher?
In the troposphere (the lowest layer of the atmosphere where weather occurs), yes. Above that in the stratosphere, temperature patterns change. But for weather science, lower altitude = warmer, higher = colder.
What grade and chapter covers altitude and temperature?
Grade 5, Chapter 3 of Amplify Science (California): Why is more water vapor getting cold over West Ferris than East Ferris?
