Beginner ELL Core Idea
- Air surrounds Earth and changes.
- Air pushes and moves.
- Heat makes air rise. Cool air falls.
- Weather happens in the troposphere.

The force created by the weight of the air above you, pushing outward in every direction.
The layer of gases that surrounds Earth and is held in place by gravity.
A state of matter with no fixed shape or volume — its particles spread out to fill any container. Air is a mix of several of these.
A force that pulls objects toward each other. On Earth, it pulls everything toward the ground.
The amount of force pushing on a given area. The same force squeezed into a smaller area means more of this.
A measure of how hot or cold something is.
The day-to-day conditions in the sky — like rain, sun, wind, or snow — at a specific place and time.
How high something is above sea level.
A tool used to measure the force of the air pushing down from above.
The parts of Earth — from deep oceans to mountain tops — where living things exist.
What something is made of, in terms of the elements and compounds it contains.
A measure of how much mass is packed into a given amount of space. More mass in the same space means a higher value.
The outermost layer of Earth's gases, where the air thins out and gradually blends into space.
The warming that happens when certain gases in the air trap heat near Earth's surface instead of letting it escape into space.
All of Earth's water — oceans, lakes, rivers, ice, and groundwater — combined.
A region high in the sky where sunlight knocks electrons loose from gas particles, leaving behind a layer of charged particles. It overlaps the mesosphere and thermosphere.
Earth's solid outer shell — the crust and the rigid upper part of the mantle beneath it.
The boundary at the top of the coldest air layer, where temperature stops dropping and starts rising again with height.
A layer of gases high above Earth with the coldest temperatures in the whole atmosphere. Most meteors burn up here.
A gas made of three oxygen atoms bonded together, which absorbs most of the Sun's harmful ultraviolet rays.
The boundary at the top of the layer where jet planes often fly, where temperature stops rising and starts dropping with height.
A calm layer above the lowest layer of air, where temperature rises with height and most of Earth's ozone is found.
The lowest layer of gases surrounding Earth, where nearly all clouds, storms, and everyday weather happen.
A layer high above Earth where the few remaining gas particles absorb intense solar energy and reach very high temperatures — even though the air there is far too thin to feel warm.
The boundary at the top of the lowest air layer, where rising air stops cooling and temperature levels off with height.
Changes or differences between one thing and another.
Water in its gas form, invisible and mixed into the air.

Order the Atmosphere
Start at the ground (troposphere) and move up to space (exosphere). Pauses mark the tops of layers.
Reading
Weather happens in the troposphere, the lowest layer. The tropopause is its top. Above is the stratosphere, then the stratopause. Next comes the mesosphere and mesopause. Higher is the hot thermosphere, and the exosphere fades into space.
Tip: Layer → pause (top) → next layer.
