Methane. The importance of methane in the greenhouse effect is its warming effect. Even though it occurs in lower concentrations than carbon dioxide, it produces 21 times as much warming as CO2.Methane accounts for 20% of the 'enhanced greenhouse effect'.ven though it occurs in lower concentrations than carbon dioxide, it produces 21 times as much warming as CO2.

On a horizontal surface, the gravitational force is equal to the object's weight, as is the normal force. But now the parallel force is the mass of the object * g * sin (theta), where g is the acceleration due to gravity (9.8 m/s^2), and theta is the angle of the inclined plane. For the perpendicular vector, the magnitude is the mass of the object * g * cos (theta).
The definition of parallel is that the sum of the angles on each side of the transversal of two lines is two right angles. From this we can show that the alternate interior angles are congruent. In our case, we have that the alternate interior angles are congruent, that is, we have that there are two pairs of alternate interior angles that are congruent, and that together one angle from each pair forms a straight angle, as you go along the lines.
