Explanation:

1. When the sun's rays fall directly on the Equator in spring, it's called the equinox. A solstice is when the sun reaches its most northerly or southerly excursion relative to the celestial equator. Axis is the imaginary line around which the Earth rotates. Tilt refers to the angle of the Earth's axis.
2. Rising carbon - dioxide levels in the atmosphere contribute to the greenhouse effect, which in turn leads to global warming. Carbon - dioxide is a greenhouse gas that traps heat.
3. Climate is defined as the long - term pattern of weather a region experiences. Temperature is a measure of how hot or cold something is. Global warming is the long - term increase in the Earth's average temperature. Humidity is the amount of water vapor in the air.

Answer:

1. D. equinox
2. C. the greenhouse effect
3. C. Climate
