Earthquakes
Where do most earthquakes occur?
Along the Ring of Fire
What is a tsunami?
A huge wave of water that may come after an earthquake and causes major destruction.
How are land animals effected by tsunamis?
They are killed by drowning.
What happens to the land during an earthquake?
It cracks opens and shakes.
What is the instrument that measures earthquakes?
A seismograph
What causes an earthquake?
When tectonic plates move and one goes over the other.
What should you do in case of a tsunami?
Get to higher elevation
How do tsunamis effect sea animals?
Sea animals are killed by pollution if dangerous chemicals are washed away into the sea, so it poisons the marine animals.
What are the effects on land AFTER an earthquake?
Death, destruction, debris, trauma, sickness, mudslide and landslaide, tsunamis, etc.
what can you do to make things more safe in and earthquake
identifying hazards, building safer structures, and providing education on earthquake safety.
How long can an earthquake last?
They’re usually very short, lasting minutes or even seconds.
Can tsunamis be predicted?
Not always, but sometimes.
How are plants effected by earthquakes?
When strong forces impact against a plant, the plant is capable of absorbing a large part of the energy because of the way plant cells slide over one another. It can cause deformation or bending of the cell wall.
What are the effects in water AFTER an earthquake?
The water becomes contaminated by all the chemicals and debris and stuff floating around.
What should you do in case of an earthquake?
Get under a table and avoid doorways and windows.
What is a fault?
A fault is a crack in Earth’s surface where the movement is happening
What happens when tsunamis get into shallow water?
It slows down but it gets much higher.
How do tsunamis effect plants?
It uproots trees and plants.
How do earthquakes affect the soil?
Earthquake motion can turn loosely packed, water-saturated soil to liquid—"liquefaction.” Liquefied soil loses its density and ultimately the ability to support roads, buried pipes, and, of course, houses.
What are the difference between P waves and S waves?
P waves are quicker but have less impact, and S waves travel slowly but have more impact. P waves travel through solids and liquids, but S waves only by solids.
What is the relationship between a volcano and earthquakes?
Both volcanoes and earthquakes occur due to movement of the Earth's tectonic plates. They both cases by the heat and energy of the earth's core
How long do tsunamis last when they get to land?
About five minutes to two hours.
Can animals tell if there is an earthquake coming? How do they react?
wild animals leave their sleeping and nesting places immediately before strong quakes and that pets become restless.
Why do tsunamis happen after an earthquakes?
The energy from an earthquake causes the ocean floor to suddenly rise or fall. This sudden displacement of the ocean floor is what typically sets a tsunami in motion. As the ocean floor rises or falls, so too does the water above it.
How often do earthquakes occur?
Around 35 per day.
