HELP ME PLZ IM IN FOURTH GRADE IT IS MY HOMEWORK WHAT IS A REGION AND A LANDFORM

To find out which region in the United States is known for its highest and lowest landforms and temperatures, you can analyze various geographic and climatic data. Here's how you can determine the answer:

1. Identify the highest and lowest landforms:
a. Start by researching the highest and lowest elevation points in the United States. The highest point is Mount Denali (formerly Mount McKinley) in Alaska, which stands at an elevation of approximately 20,310 feet (6,190 meters). The lowest point is Death Valley in California, which sits at an elevation of roughly 282 feet (86 meters) below sea level. So, Alaska and California hold the records for the highest and lowest landforms in the US, respectively.

2. Determine the regions with extreme temperatures:
a. Look for temperature records and extremes in different states. The coldest recorded temperature in the contiguous United States occurred in Prospect Creek, Alaska, at -80 degrees Fahrenheit (-62 degrees Celsius). On the other hand, the highest recorded temperature in the US is 134 degrees Fahrenheit (56.7 degrees Celsius), registered in Death Valley, California. Therefore, Alaska and California are also known for extreme temperatures.

In summary, Alaska (Mount Denali) holds the highest landform record, and California (Death Valley) holds the lowest landform record. Additionally, Alaska (Prospect Creek) claims the lowest temperature record, and California (Death Valley) holds the highest temperature record in the United States.
