Limiting and Predicting Constructive and Destructive Processes

Front

What is a levee?

Back

A levee is a structure built along the sides of rivers or coastal areas to prevent flooding.

Front

What instrument is used to measure seismic waves?

Back

A seismograph is an instrument that records seismic waves produced by earthquakes.

Front

What does a seismograph show scientists?

Back

A seismograph shows time, location, depth, and energy of seismic waves.

Front

What is the purpose of a dam?

Back

A dam is built to hold back water and prevent flooding in nearby areas.

Front

What is a tsunami?

Back

A tsunami is a series of large ocean waves caused by underwater earthquakes or volcanic eruptions.

Front

What instrument is used to predict tsunamis?

Back

DART (Deep-ocean Assessment and Reporting of Tsunamis) is used to predict tsunamis.

Front

What is the role of seismographs in predicting earthquakes?

Back

Seismographs help scientists detect and analyze seismic activity to predict earthquakes.

Front

What are constructive processes in geology?

Back

Constructive processes are natural events that build up landforms, such as volcanic eruptions and sediment deposition.

Front

What are destructive processes in geology?

Back

Destructive processes are natural events that wear down landforms, such as erosion and weathering.

Front

How do scientists use seismographs to study earthquakes?

Back

Scientists analyze the data from seismographs to determine the strength and location of earthquakes.
