Deforestation: the action of clearing a wide area of trees.
Climate change: Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth's surface is warming, and many of the warmest years on record have happened in the past 20 years.

Answer:
only 3
Explanation:
probably 4 too, I'm not sure
Is similar to 3 an you nedd múltiple by 5 and you get 15 for the result
1) Option b: gas pressure.
This is sustainted by the kinetic molecular theory of the gases.
2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.
PV = nRT
If V and n are constant, P is proportional to T, then if T increase P will increase too.
1 moles of any molecules has 6.022 x 10^23 molecules in it
