Different parts of Earth's surface receive different amounts of sunlight. The sun's rays strike Earth's surface most directly at the equator. ... Because of the Earth's tilt the sun's rays strike the surface at a slant at the poles; they are less focused. This spreads the rays over a wide area.
Answer:
The true statement is option D. The two major factors determining the Earth's temperature are the Earth-Sun distance and the concentration of oxygen in the atmosphere.
Explanation:
The distance between the sun and the Earth is one of the factors that determines the temperature of the planet. The energy from the sun travels to the Earth, increasing the temperature.
The other fact that has a role in the Earth's temperature is the concentration of oxygen in the atmosphere. It can increase or decrease the temperature according to the amount of this. Oxigen contributes to the greenhouse effect, which helps to keep the temperature in a range that allows life to happen.
