Explanation:
Alfred Wegener in 1915 published 'The Origin of Continents and Oceans'. But geologists denounced his theory. Wegener's Continental drift is the theory that the different continents of the planet earth have moved over time causing them to shift positions. he thought all continents were once joined together before breaking up to different positions.
Part of the objections he faced was because he did not have much evidences to back up his theory.
Answer:
When a line bisects an angle, it divides the angle into two congruent angles.
Angle FGH = Angle HGI
4x - 6 = 5x - 15
x = 9
Substitute x into angles.
Angle FGH = 4(9) - 6 = 30°
Angle HGI = Angle FGH = 30°
Angle FGI = Angle FGH + Angle HGI
= 30 + 30
= 60°
Answer:
The stratosphere contains ozone which traps solar radiation
Explanation:
Increase in temperature with increase in altitudes in the stratosphere is caused by the presence of ozone which traps solar radiation thus causing temperature to increase in the stratosphere with increase in altitude.
