Constructive Forces
What is a constructive process that can create new surface features underwater?
Volcanism
What is a destructive force that can change the landscape?
Erosion or earthquakes.
What happens during an earthquake that can change the Earth's surface?
The ground shakes and can cause shifts in land.
How can volcanic eruptions create new land?
By depositing lava that cools and hardens.
What technology is used to monitor earthquakes?
Seismographs.
How do tectonic plates create mountains?
By colliding and pushing against each other, which is a constructive process.
What is an example of an event that is destructive to land?
An earthquake.
How do scientists model the effects of earthquakes?
By using interactive models with clay blocks to represent tectonic plates.
What is the main cause of the Hawaiian Islands forming?
Volcanic hot spots creating islands over time.
What do seismographs measure?
The intensity and duration of seismic waves during an earthquake.
What evidence supports that volcanoes can be constructive forces?
Volcanic eruptions expand the sea floor and create islands.
What are seismic waves?
Waves of energy caused by the sudden movement of the Earth's crust.
What can seismological studies reveal about earthquakes?
They can show patterns of earthquake activity and identify potential risks.
What happens when lava cools after an eruption?
It forms new land features, such as islands or mountains.
What technology helps track volcanic activity?
Seismology tools and satellite imagery.
How do volcanic eruptions affect the sea floor?
They create new landforms by depositing lava.
What is a major destructive force in California?
Earthquakes due to fault lines.
Why is it important to build structures that can withstand earthquakes?
To minimize damage and protect lives during seismic events.
What materials are used to study volcanic eruptions?
Seismology tools and satellite imagery.
How can seismology help in understanding tectonic plate movements?
By recording and analyzing the data from seismic activity.
Why do scientists study the "Ring of Fire"?
To understand the relationship between volcanic activity and earthquakes.
What are some consequences of earthquakes in populated areas?
Structural damage, injuries, and displacement of people.
How can earthquakes lead to volcanic eruptions?
By causing shifts that release pressure on magma reservoirs.
What is the relationship between tectonic plates and volcanic activity?
Movement of tectonic plates can lead to volcanic eruptions.
What types of questions can seismology answer about the Earth's surface?
Questions about earthquake patterns, frequency, and the impact of seismic events.
