Which of the following locations would receive the most concentrated energy from the sun?
- A location at 30° latitude
- A location at 0° latitude (correct)
- A location at 60° latitude
- A location at 90° latitude
Why do places at higher latitudes tend to have colder climates?
Why do places at higher latitudes tend to have colder climates?
- Because they receive less concentrated energy from the sun (correct)
- Because they receive more direct energy from the sun
- Because they are farther from the moderating influence of the ocean
- Because they receive more scattered energy from the sun

Study Notes
Latitude and Climate
- Latitude measures how far north or south a place is from the equator, and is measured in degrees.
- Places closest to the equator (0º latitude) receive more concentrated, direct energy from the sun.
- Areas at higher latitudes (farther from the equator) receive energy from the sun that is spread over a larger area and is less concentrated.
- Lower latitudes tend to have warmer climates than higher latitudes.
Altitude and Climate
- Altitude affects local climate, with temperatures becoming cooler as altitude increases.
- This is due to air density, with air molecules being spaced farther apart at higher altitudes, making the air less dense.
- At lower altitudes, air molecules are closer together, making the air more dense, and trapping heat, resulting in warmer temperatures.
Bodies of Water and Climate
- Bodies of water take a long time to heat up or cool down compared to the surrounding land.
- This helps keep nearby temperatures from becoming too extreme.
- In winter, heat from bodies of water warms the air above, which then blows over the land, warming it.
