Learning the Physical Patterns in a Changing World

Physical patterns are those natural features on Earth that repeat or follow a structure. Examples include mountain ranges, lots of river systems, many deserts, and climate zones.

These patterns are formed by processes like plate tectonics, erosion, weathering, and volcanic activity.

• Plate Tectonics – Movement of Earth’s crust creates mountains and earthquakes.
• Erosion – Wind, water, and ice wear down land.
• Volcanic Activity – Creates new land and reshapes landscapes.
• Weathering – Breaks rocks into smaller pieces over time.

Humans also change a lot of physical patterns through:

• Building cities and roads
• Deforestation
• Mining and drilling
• Agriculture

These activities can create opportunities (jobs, transportation) but also challenges (pollution, habitat loss).

Opportunities:

• Farming near rivers
• Tourism in mountain regions
• Renewable energy from wind and water

Challenges:

• Flooding
• Earthquakes
• Droughts
• Climate change
