Constructive Forces
What is a landform created by the build-up of sediment at the mouth of a river?
Delta
What process breaks down rocks into smaller pieces?
Weathering
What process involves the movement of sediment from one place to another?
Weathering
What technology helps predict earthquakes?
Seismology
Give an example of a fast-changing process.
Flood or Earthquake
Name one process that creates mountains.
Tectonic plate shift
Name a natural disaster that can erode land quickly.
Flood
Name one factor that can speed up weathering.
Water
How do GIS maps assist in flood forecasting?
They show areas at risk of flooding
Which process takes a long time to change the landscape?
Erosion, weathering, or deposition
How do sand dunes form?
Sand movement by wind
How do Landslides occur?
Movement of rock and soil down a slope
Describe how deposition occurs
Sediment being dropped off in a new location
Name a construction method that helps protect against earthquakes.
Using stronger materials like steal or metal to avoid crumbling
How do volcanic eruptions change the landscape quickly?
The lava creates new Islands
What is the term for the process through which sediments are dropped in a new place?
Deposition
What is the impact of heavy rain on hills or mountains?
Erosion and landslides
How does freezing and thawing contribute to weathering?
It causes rock to crack and break apart
How does satellite imagery help scientists?
Allows them to monitor any changes in the landscapes
Describe how a river can change its path over time.
Through erosion and sediment deposition
Describe how Islands are formed.
Through lava and a volcanic eruption
Explain how glaciers can shape the landscape.
Through erosion when they move across the land
Explain how plants can affect erosion.
Their roots hold soil together and help prevent erosion
Explain the importance of technology in predicting volcanic eruptions.
Helps scientists warn communities before an eruption so they can evacuate
What is the difference between constructive and destructive processes?
Constructive forces build up land while destructive forces break the land down
