quick answers
Bottom of Page 4: Low-pressure systems form at ____________ latitudes (like the equator). This is why the climate at the equator is so wet.

High-pressure systems form at _____________ latitudes (like the poles), which is why they are drier.

Reminder from Lesson 2- The equator is the hottest part of Earth because it receives the sun’s most direct rays.
What is the polar jet stream?



The polar jet stream occurs at _________ latitude. The jet stream forms when the cold air from 30o-60o latitude meets the warm air between 60o-90o latitude.

What direction does the polar jet stream move? What is the average speed?

Answer 1

Low-pressure systems form at **tropical** latitudes (like the equator). High-pressure systems form at **polar** latitudes (like the poles).

The polar jet stream occurs at **30 to 60 degrees** latitude.

The polar jet stream moves from **west to east**. The average speed is **approximately 100 to 200 miles per hour**.
