Which statement explains what happens to air temperature as elevation increases and why? As elevation increases, air pressure in
2 answers:
Answer:
Option C, As elevation increases, air pressure decreases, molecules spread out, and air temperature cools.
Explanation:
As we move towards the sky the number of air particles reduces and hence its density also reduces. Due to lesser number of particles the pressure exerted by air also reduces at high elevations.
As per the gas law
Where P is the pressure, V is the volume, n is the number of mole, R is the gas constant and T is the temperature.
Gas law states that if volume is constant, the relation between temperature and pressure is proportional.
Thus, if pressure is reducing the temperature will also reduce.
Hence, option C is correct

The main aspect used to differ coniferous tree are their leaves. Coniferous leaves look like elongated needles, instead of the regular flatend out leaves we're used to
Further characteristics:
Seeds are hard and grow in large groups, stuck to eachother.
Coniferous are evergreen trees (don't shed leaves nor change the colour of these, although this rule does not apply to all of them).
They have spread worldwide.
Can withstand low temperaurees and can be found even in places like the Artic circle.
