2A2 - Geographical Cause and Effect Flashcards
Explain the cause and effect of practical geographical concepts.
What is the study of the Earth’s natural physical features and human interactions with those features called?
Geography
What is the study of the Earth’s atmosphere and long-term weather patterns over a particular region called?
Climatology
What is defined as the long-term patterns of weather-related variables within a particular region?
Climate
What determines how much solar energy is reflected back into the atmosphere or absorbed and converted to heat?
Topography and nature of the ground surface.
How does latitude affect climate?
- Latitudes closer to the equator receive more direct and less variable solar energy input and thus have minimal seasonal temperature variations (highs and lows).
- Latitudes closer to the poles have seasonally variable solar input and thus higher seasonal temperature variations.
How does elevation affect climate?
- Air temperatures decrease with height in the troposphere.
- Air temperatures become colder as one moves up and away from this heat source.
This is because air easily loses heat while earth surface materials (water, rock, soil, vegetation) are more efficient heat storage media. Therefore, the earth surface is the major heat source in the lower atmosphere.
How do major mountain ranges affect climate?
They commonly represent climate divides.
What role do large bodies of water play in climate?
They provide sources of moisture through evaporation.
What is the major heat source in the lower atmosphere?
The Earth’s surface.
What is the significance of latitude on average temperatures in different cities?
Average winter and summer temperatures increase as one moves towards the equator.
What role do the Himalayan Mountains play in influencing climate?
They block colder air from Northeast Asia in winter and force water-laden air to lose moisture, causing heavy precipitation in summer.
This results in an arid climate north of the mountains.
How does water impact seasonal temperature differences in coastal areas?
Water moderates seasonal temperature differences, leading to cooler summers and warmer winters in coastal areas compared to inland regions.
Water absorbs and releases heat more slowly than other earth surface materials.
What are the four main geographic variables that affect climate?
- Latitude
- Elevation
- Topography
- Water
Each variable has a unique influence on air temperature and precipitation patterns.
Why is the link between geography and climate important?
They are interconnected by physical and chemical processes that cannot be fully understood without considering both fields.
They involve complex, dynamic interactions over various time scales.
What are the four common types of climates?
- Tropical
- Dry (arid)
- Temperate
- Polar
Each type is characterized by specific temperature and precipitation patterns based on geographic location.
