geography lab review Flashcards
Title:
Describes what the map represents.
Legend:
Explains the symbols used on the map.
Scale:
Indicates the relationship between distances on the map and the real world.
Mercator Projection:
Distorts area, especially near the poles.Preserves angles and shapes for navigation.
Peters Projection:
Equal-area projection; preserves relative sizes of landmasses.
Distorts shapes.
Robinson Projection:
Balances distortions in area, shape, distance, and direction.
Latitude:
Horizontal lines measuring distance north or south of the Equator (0° to 90°).
Longitude:
Vertical lines measuring distance east or west of the Prime Meridian (0° to 180°).
Passive sensors
depend on sunlight or thermal energy from the surface.
Active sensors
have their energy source, allowing data collection day or night.
Satellite Imagery Interpretation
Different surfaces reflect light in unique ways, like a fingerprint. Urban areas reflect a lot of light in both visible and infrared ranges, making them easy to identify.
GIS Layers:
Each layer represents a type of data (e.g., physical, social, environmental).
Understanding Solar Declination
The solar declination influences the intensity and duration of sunlight received at different latitudes, driving seasonal variations.
Solar Angle
The solar angle determines the intensity of sunlight at a location. Higher angles correspond to more direct sunlight, increasing energy absorption.
Solar Altitude:
The angle of the Sun above the horizon at a specific time and location.
Insolation (Incoming Solar Radiation):
The amount of solar energy received per unit area, which depends on the angle of incidence and atmospheric conditions.
Seasonal Changes:
Caused by Earth’s axial tilt and orbit around the Sun, resulting in varying day lengths and solar angles.
Energy Budget:
Balance between incoming solar radiation (shortwave) and outgoing terrestrial radiation (longwave).
Cloud Formation:
Clouds form when air cools to its dew point, and water vapor condenses onto aerosols.
Factors influencing cloud formation include temperature, humidity, and atmospheric lifting.
Air Masses:
Large bodies of air with uniform temperature and moisture characteristics.
Atmospheric Lifting Mechanisms:
Convergent Lifting: Air flows toward a central point and rises.
Convectional Lifting: Warm air rises due to heating from the surface.
Orographic Lifting: Air is forced upward by mountains.
Frontal Lifting: Warm air rises over cold air along a front.
