While exploring a fossil site, you find a bunch of fossil leaves with jagged edges. What could you infer about the climate from which they came?
1. They produce maple syrup because they belong to a maple tree.
2. They came from a warm climate because jagged leaves are found in really hot climates.
3.They came from a very dry climate because jagged leaves are formed when there is a drought.
4. They came from a cold climate because jagged leaves are found in colder climates
