Spheres
This sphere includes all the air surrounding Earth.
What is the atmosphere?
Liquid water changes into water vapor and rises into the atmosphere during this process.
What is evaporation?
In this first step, engineers identify the problem and learn about the requirements.

What is gravel or small rocks?
This is the largest animal in the world.
What is the blue whale?
Rivers, oceans, glaciers, groundwater, and clouds are all part of this sphere.
What is the hydrosphere?
Water vapor cools and changes into tiny liquid droplets that form clouds.
