Air masses and fronts review worksheet featuring a map of South America and a table for identifying air mass characteristics.

Problem Overview:

The task involves analyzing a map of South America and identifying the air masses present in different regions. The goal is to complete a table by determining the temperature, humidity, and name of the air mass for each labeled location (A, B, C, D, E) on the map.

Step-by-Step Solution:

#### 1. Understanding Air Masses:
From the provided table in the image, we have the following air masses and their characteristics:

| Type | Where It Forms | Temperature (Warm or Cold) | Humidity (Wet or Dry) |
|---------------------|----------------------|-----------------------------|------------------------|
| Continental Polar | Over land | Cold | Dry |
| Continental Tropical (CT) | Over land | Warm | Dry |
| Maritime Polar | Over ocean | Cold | Wet |
| Maritime Tropical (MT) | Over ocean | Warm | Wet |

#### 2. Analyzing the Map:
The map shows South America with five labeled locations (A, B, C, D, E). To determine the air masses at these locations, we need to consider their geographical positions and proximity to oceans or continents.

- Location A: This is near the northern coast of South America, specifically in the Caribbean region.
- Location B: This is over the Amazon rainforest, which is inland.
- Location C: This is along the eastern coast of Brazil, near the Atlantic Ocean.
- Location D: This is over the southern part of South America, near Patagonia.
- Location E: This is over the Pacific Ocean, west of South America.

#### 3. Determining Air Masses:
Using the characteristics of air masses and the geographical context of each location:

- Location A (Caribbean region):
- Proximity: Near the ocean.
- Climate: Warm and humid due to its tropical latitude and ocean influence.
- Air Mass: Maritime Tropical (MT).
- Temperature: Warm.
- Humidity: Wet.

- Location B (Amazon rainforest):
- Proximity: Inland, over land.
- Climate: Warm and relatively dry compared to the coast (due to being inland).
- Air Mass: Continental Tropical (CT).
- Temperature: Warm.
- Humidity: Dry.

- Location C (Eastern coast of Brazil):
- Proximity: Near the Atlantic Ocean.
- Climate: Warm and humid due to ocean influence.
- Air Mass: Maritime Tropical (MT).
- Temperature: Warm.
- Humidity: Wet.

- Location D (Southern part of South America):
- Proximity: Inland, over land.
- Climate: Cold and dry due to its southern latitude and distance from the ocean.
- Air Mass: Continental Polar.
- Temperature: Cold.
- Humidity: Dry.

- Location E (Pacific Ocean, west of South America):
- Proximity: Over the ocean.
- Climate: Cold and wet due to its high latitude and ocean influence.
- Air Mass: Maritime Polar.
- Temperature: Cold.
- Humidity: Wet.

#### 4. Completing the Table:
Based on the analysis above, we can fill in the table as follows:

| Letter | Temperature (Warm/Cold) | Humidity (Wet/Dry) | Name of Air Mass (CP, CT, MP, MT) |
|--------|--------------------------|---------------------|------------------------------------|
| A | Warm | Wet | MT |
| B | Warm | Dry | CT |
| C | Warm | Wet | MT |
| D | Cold | Dry | CP |
| E | Cold | Wet | MP |

Final Answer:

\[
\boxed{
\begin{array}{|c|c|c|c|}
\hline
\text{Letter} & \text{Temperature (Warm/Cold)} & \text{Humidity (Wet/Dry)} & \text{Name of Air Mass (CP, CT, MP, MT)} \\
\hline
A & \text{Warm} & \text{Wet} & \text{MT} \\
B & \text{Warm} & \text{Dry} & \text{CT} \\
C & \text{Warm} & \text{Wet} & \text{MT} \\
D & \text{Cold} & \text{Dry} & \text{CP} \\
E & \text{Cold} & \text{Wet} & \text{MP} \\
\hline
\end{array}
}
