When water evaporates from a lake, what spheres are interacting?

Plants, trees, flowers, humans, animals are found in this sphere.
Biosphere
A boy is throwing snowballs. What spheres are interacting?
Biosphere (boy) and hydrosphere (snowball)
How many spheres make up the Earth's System?
4 spheres
This sphere includes all of the water on Earth.
What is the hydrosphere?
When a forest is on fire, what spheres are interacting?
Biosphere (trees and animals) and Atmosphere (air). The trees and animals are dying from the fire. The air is becoming filled with smoke.
Rock, dirt, and the inside of the Earth are in this sphere.
The geosphere?

Some physical processes or events take decades to change our earth while others can change our earth in a day. Name three physical processes that can change Earth in a day?
volcano eruptions, tsunamis, hurricanes, tornados, flash floods, etc.
Which of the following is NOT a part of the water cycle?

Name all the spheres and what they contain!
Hydrosphere-Water
Biosphere- Life
Atmosphere- Gases
Geosphere-Solid/Rock
Explain how a volcano eruption involves interactions of all four spheres.
Geosphere (rock) and Atmosphere (air) Also, the Geosphere (rock) and Biosphere (humans). The volcano erupts and shoots lava and gases into the atmosphere. The lava pours down the volcano and can kill humans or animals in its path.
What is the most abundant type of water on Earth? What is the percentage?
Salt water- 97%
