To determine which two essential elements of geography are missing from the image, we need to consider the key elements of geography. The main elements typically include:
- Location - where things are found on the earth.
- Place - characteristics that make a location unique.
- Human Systems - how people interact with their environment, including cultures, economies, and urban systems.
- Physical Systems - natural processes and features of the earth.
- Movement - how and why people and goods move.
- Region - areas that have common features.
Now, let's analyze the options provided to find the two missing elements:
A. “Human systems” and “Physical systems” - This option suggests that both important aspects that involve human interaction and natural features are missing.
B. “Human geography” and “Human systems” - This combines a broader area of study with human interaction, but it is somewhat redundant as "human geography" relates directly to "human systems."
C. “Physical geography” and “Movement” - This highlights the physical aspects and the dynamics of movement but does not touch upon human interaction.
D. “Human systems” and “Location” - This indicates a missing element about human interactions and the concept of location.
Based on these analyses:
- If the image lacks "Human systems," the interaction of people and their environment is not depicted.
- If it also lacks "Location," the positioning of features on Earth is not represented.
Therefore, the correct answer concerning the two essential elements of geography that are missing would be:
D. “Human systems” and “Location.”
