What causes a direct rise in CO2 emissions? A. burning more fossil fuels
B. population growth
C. increased solar activity
D. shrinking habitats

A. burning more fossil fuels

Explanation:

The majority of direct emissions are caused by the use of fossil fuels for energy Indirect emissions are caused by the use of fossil fuels to generate electricity, which is then used by an industrial facility to power industrial buildings and machinery. The majority of direct emissions are generated by the use of fossil fuels for electricity. Indirect emissions are emitted when fossil fuels are burned to generate energy, which is then used to power industrial buildings and machinery by an industrial facility.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.
