Water in the Air

Front

Meteorologists Noun

---

[mee-tee-er-ol-uh-jists]

Back

Meteorologists

---

Scientists who study the atmosphere and its phenomena to understand and predict weather and climate patterns.

---

Example: Meteorologists use models to study variables like temperature and humidity to predict weather.

Front

Humidity Noun

---

[hyoo-mid-i-tee]

Back

Humidity

---

A measure of the amount of invisible water vapor that is present in the air.

---

Example: The image uses water droplet icons to show different humidity levels, helping students understand how much water vapor is in the air.

Front

Air Pressure Noun

---

[air presh-er]

Back

Air Pressure

---

The force exerted onto a surface by the weight of the air above it.

---

Example: The image shows how air pressure is higher at lower altitudes and lower at higher altitudes using a seesaw analogy.

Front

Troposphere Noun

---

[troh-puh-sfeer]

Back

Troposphere

---

The lowest layer of Earth's atmosphere where most weather conditions and phenomena occur.

---

Example: The troposphere is the lowest layer where weather happens, shown with clouds and mountains.

Front

Radiosonde Noun

---

[rey-dee-oh-sond]

Back

Radiosonde

---

A small package of instruments carried by a weather balloon to measure atmospheric conditions and transmit data.

---

Example: A weather balloon with waves shows how a radiosonde sends data about the atmosphere.

Front

Stratosphere Noun

---

[strat-uh-sfeer]

Back

Stratosphere

---

The layer of the Earth's atmosphere situated just above the troposphere and below the mesosphere.

---

Example: The image shows the stratosphere as a distinct layer above the troposphere and below the mesosphere.

Front

Sensors Noun

---

[sen-sers]

Back

Sensors

---

Devices designed to detect or measure a physical property and record, indicate, or otherwise respond to it.

---

Example: A temperature sensor detects and displays the air temperature, showing how sensors measure physical properties.

Front

Transmitter Noun

---

[trans-mit-er]

Back

Transmitter

---

An electronic device that generates and sends out signals, such as radio waves, to convey information.

---

Example: A phone connected to a circuit with batteries shows how signals are transmitted using a transmitter.

Front

Biodegradable Adjective

---

[bahy-oh-di-grey-duh-buhl]

Back

Biodegradable

---

Capable of being decomposed and broken down into natural elements by bacteria or other living organisms.

---

Example: The image shows a bin labeled 'Biodegradable' with food waste, illustrating materials that can decompose naturally.

Front

Coordinated Universal Time (UTC) Noun

---

[koh-awr-dn-ey-tid yoo-nuh-vur-suhl tahym]

Back

Coordinated Universal Time (UTC)

---

The primary time standard by which the world regulates clocks, used for synchronized global weather observations.

---

Example: This map shows how Coordinated Universal Time (UTC) is used worldwide to regulate clocks.
