1 Which is the link between fossil fuel use and flowers blooming earlier in the spring season?(1 point)
Spring seasons are cooler due to increased fossil fuel emissions.
A warmer Earth due to fossil fuel emissions has milder winters and earlier springs.
Fossil fuel emissions contain compounds that are fertilizers.
Increased greenhouse gases due to fossil fuel emissions allows more sunlight to reach Earth.

4 Which are true about changes in carbon dioxide in the Earth's atmosphere since 1860? Select the two correct answers.(1 point)
Responses
The increases in carbon dioxide are caused by human activity.
The changes are triggered by a new interglacial period.
The rate of change in carbon dioxide is exponential.
The increases in carbon dioxide can be explained by the Milankovitch cycle.
