If only one half of the flora in the world existed in 2100 (perhaps due to
deforestation), what do you predict the atmospheric carbon level would be?
how would you change the simulation to reflect this?

The carbon level would be higher because there is less flora and the carbon would be absorbed at a slower rate. There would not be a good plant to carbon ratio to balance out the carbon levels in the atmosphere.

Explanation:

the answer would be knowledge about cars!

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
