Suggest improvements for the highlighted problem area:
The Amazon drains water from a region that is large, tropical and flat. This region is 13 times the size of France but little of the river water comes from mountain snow melt. Most of it's water comes from rain in the vast lowlands. This rain forest, located on the equator experiences the equivalent of two summers each year. The result is two seasonal peaks of rainfall and streamflow. In an area as flat as the Amazon basin, these peaks can cause widespread damage. Floods are common in the city of Manaus, which is 1200 kilometers inland but only 26 meters above sea level.
Answer:
- A Comma for a Clause -
Another mistake with commas can be found in the second sentence of our opening paragraph:
This region is 13 times the size of France but little of the river water comes from mountain snow melt.
In this sentence we have the conjunction but introducing an independent clause. (This clause is called independent because it can be a complete sentence all by itself.) A comma should be placed in front of any conjunction that introduces an independent clause:
This region is 13 times the size of France, but little of the river water comes from mountain snow melt.
