Seasonal changes are due to _________ and Earth's ______. alatitude; elevation blatitude; tilt crotation; tilt delevation; rotation

The answer is b. Seasonal changes are due to latitude and Earth's tilt.

Step 1: Understand the question. The question is asking what causes seasonal changes on Earth.

Step 2: Know the facts. The Earth's tilt on its axis and its orbit around the sun cause the seasons.

Step 3: Apply the facts to the question. The Earth's tilt (23.5 degrees) causes the sun's rays to hit different latitudes (distances from the equator) at varying angles at different times of the year.

Step 4: Choose the correct answer. The answer is b. latitude; tilt. Latitude refers to the distance from the equator (measured in degrees), and tilt refers to the Earth's tilt on its axis.
