Lesson 16.4: Critical Reading

Name___________________ Class______________ Date________

Read this passage based on the text and answer the questions that follow.

Collecting Weather Data

Weather stations are devices that contain many instruments for measuring weather conditions. There are thousands of weather stations all over the world. Many are on land. Some float on the oceans attached to buoys. There’s probably at least one weather station near you.

Other weather devices are used to collect weather data in the atmosphere. They include weather balloons, satellites, and radar.

  • A weather balloon carries instruments for measuring weather conditions. It rises into the atmosphere until it bursts. As it rises, it gathers weather data and sends them to the surface.
  • Many weather satellites orbit Earth. They constantly collect and transmit weather data from high above the surface.
  • A weather radar device sends out radio waves in all directions. The waves bounce off water in the atmosphere and return to the radar device. The radar data show where precipitation is falling.


  1. What are weather stations? Where are they found?
  2. Describe how weather balloons and weather satellites are used to collect weather data.
  3. Explain how radar is used to find where precipitation is falling.
