How do scientists use infrared cameras in satellites?

Question

to study the growth of plants
to count the number of fish in the ocean
to protect whales while they are breeding
to warm polar regions of Earth

Answer 1

Scientists use infrared cameras in satellites to study the growth of plants. Infrared cameras can detect the amount of heat and light that plants emit, which indicates how much photosynthesis is occurring. This information can be used to track the health of crops, monitor deforestation and other land use changes, and assess the impact of climate change on ecosystems. They are not used to count the number of fish in the ocean, protect whales while they are breeding, or warm polar regions of the Earth.
