Geography: Water Sources and Landforms

Study Notes

Geography

Geography is the study of the Earth's surface, including its physical features, climate, populations, and the interactions between them.
Key aspects include spatial distribution, patterns, and processes, encompassing both human and physical elements.
It blends multiple disciplines like geology, biology, and sociology.

Water Sources

Water sources are essential for life and diverse in nature.
Surface water sources include rivers, lakes, and wetlands.
Groundwater collects beneath the earth's surface in aquifers.
Water availability varies greatly depending on location and climate.
Glacial ice is a significant freshwater reservoir, though often inaccessible.
Human activities significantly affect water availability and quality. Deforestation reduces water infiltration, while reforestation increases it.

Landforms

Landforms are natural features of the Earth's surface, differing in their structure and composition.
Examples include mountains, plateaus, plains, valleys, canyons, and coastal features.
These landforms are sculpted by various geological processes.
Volcanic activity creates unique landforms like volcanic mountains and caldera.
Erosion, weathering, tectonic plate movement, and deposition are all key factors in shaping landforms.

Natural Disasters

Natural disasters are unexpected, often severe events originating from natural processes.
Examples include earthquakes, volcanic eruptions, floods, hurricanes, tsunamis, droughts, wildfires, and landslides.
These disasters have significant impacts on human populations and environments.
They can cause loss of life, destruction of property, displacement, and long-term economic hardship.
Vulnerability to these events can be linked to geography, population density, and infrastructure.

Climate Regions

Climate regions are large areas that share similar weather patterns over a long period.
Criteria such as temperature, precipitation, humidity, and wind patterns are used to define these regions.
Temperature and precipitation are key determining factors of climate regions.
Common climate regions include tropical, arid, temperate, polar, and highland.
Climate zones are further subdivided into specific climates, each with particular characteristics.

Tectonic Plates

Tectonic plates are large, rigid pieces of Earth's lithosphere that move slowly and interact at plate boundaries.
Their movement is a key driver of geological processes.
Types of boundaries include divergent, convergent, and transform.
Convergent boundaries can create mountains, volcanoes, and deep ocean trenches.
Divergent boundaries are often associated with mid-ocean ridges and volcanic activity.
Transform boundaries can cause earthquakes.
The positions of continents change gradually over geologic time as a result of plate tectonics.
Plate movement has significant effects on landforms, earthquakes, and volcanic activity.
Major geological events, like mountain building and the creation of ocean basins, are largely a result of plate movement.
