Which of the following can have a significant effect on a region's climate?

a. only ocean currents
b. ocean current, mountains, elevation and latitude
c. only the mountains
d. only elevation and latitude

The answer would be B.

This is because if a region is;

Near an Ocean, it would have a more humid climate, depending on the time of year.

Near a Mountain, it would have a warmer climate or colder climate, depending on the time of year.

At either a high or low Elevation it would be warm or cold, also depending on the time of year.

At a certain Latitude, ex. if it's near the equator, it would be warmer and if it was closer to the poles, it would be colder

Hope this helps! :)
