What is a biodiversity hotspot?
A biodiversity hotspot is a region with a high number of species, many of which are found nowhere else, and that is under threat.

C. Troposphere
Which of the following is a reason why CO₂ occurs naturally in the atmosphere? (What does it do?)
It traps heat, helps regulate temperatures, and makes the Earth habitable.
Name the four spheres of the Earth.

True.
Give one example of how two or more of the Earth’s spheres can interact.
Example: A volcanic eruption (lithosphere) releases ash and gases into the atmosphere, destroys habitats (biosphere), and can change river paths or water qualit

Why is nitrogen important in the atmosphere?
Nitrogen is important because it is essential for plant growth, which in turn supports other life forms on Earth.
What is biodiversity?
