Final answer:
Capitalization corrections: 'Southwest' and 'Park' are part of a proper noun and should be capitalized, while 'winter' should not be capitalized as it is not used as a title here. Bryce Canyon is known for its distinctive rock formations formed by a combination of 'frost-wedging' and chemical weathering.
Step-by-step explanation:
In the given text, there are four capitalization errors that need to be corrected:
- 'southwest' - should be capitalized as 'Southwest' because it refers to a specific region.
- 'park' - should be capitalized as 'Park' because it refers to Bryce Canyon National Park.
- 'Winter' - should be capitalized as 'winter' because it is not the start of a sentence or a proper noun.
The corrected sentence would be:
If you go to the Southwest, visit Bryce Canyon National Park to see one of the region's most distinctive features: colorful spikes of rock formed by erosion.
Seeing these rock formations in the winter is a special treat, because the melting snow makes their colors appear more vibrant.
