Question

question 9
lines connecting points of equal latitude are called:
○ meridians
○ time zones
○ great circles
○ parallels
question 10
at the summer solstice in the northern hemisphere, at what latitude do the suns rays strike the earth at a 90 - degree angle?
○ the tropic of cancer
○ the north pole
○ the arctic circle
○ the equator

Explanation:

For Question 9: Lines of equal latitude run east-west and are defined as parallels. Meridians are lines of equal longitude, great circles are circles that divide the Earth in half, and time zones are based on longitude.
For Question 10: During the Northern Hemisphere summer solstice, the Sun's direct rays reach their northernmost point, which is the Tropic of Cancer (23.5°N). The Equator gets direct rays at equinoxes, the Arctic Pole has 24-hour daylight but not direct 90° rays, and the Arctic Circle marks the start of the midnight sun zone.

Answer:

Question 9: D. Parallels
Question 10: A. The Tropic of Cancer
