What is an earthquake best described as?
An earthquake is best described as. the sharp release of energy in the Earth’s crust that creates seismic waves.
Which of the following best describes why the 2010 earthquake in Chile caused a large tsunami while the 2010 earthquake in Haiti only caused a small and local tsunami View Available hint S Which of the following best describes why the 2010 earthquake in Chile caused a large tsunami while?
The earthquake in Haiti was the result of motion on a transform boundary, which does not produce any vertical motion of the sea floor, whereas the Chilean earthquake was the result of motion along a convergent plate boundary, which does. The Chilean earthquake was much larger and thus able to produce a tsunami.
Which statement best describes the epicenter of an earthquake?
Which of the following responses best describes the epicenter of an earthquake? The point on Earth’s surface directly above the focus of an earthquake.
Which of the following best describes the general relationship between the velocity of seismic waves and depth in Earth view available hint S Which of the following best describes the general relationship between the velocity of seismic waves and depth in Earth the velocity of seismic waves is the same until they?
Which of the following best describes the general relationship between the velocity of seismic waves and depth in Earth? The velocity of seismic waves generally increases with depth. In general, body (P) waves would travel fastest in the inner core and slowest in the outer core.
When was Alaska’s last earthquake?
| Mag | Earthquake Information | Depth |
|---|---|---|
| 1.1 | August 25, 11:11 PM 2 mi NW of Mt. Martin | 0 miles |
| 2.0 | August 25, 10:29 PM 65 mi SE of Yakutat | 4 miles |
| 1.3 | August 25, 10:13 PM 15 mi NW of Ninilchik | 124 miles |
| 1.9 | August 25, 10:06 PM 15 mi S of Mt. Gareloi | 27 miles |
What is the description of earthquake epicenter?
The epicenter is the point on the earth’s surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.
Where is the epicenter of earthquake?
The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.
What happens to S and P waves as they travel inside Earth?
S waves cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium. When the waves cross the boundary between two different layers, there is a sudden change in direction due to refraction. …
Which is true of the point above the focus of an earthquake?
The point on Earth’s surface directly above the focus of an earthquake. Nice work! You just studied 41 terms! Now up your study game with Learn mode. Which of the following are true of earthquakes?
What’s the difference between a plate boundary and an earthquake?
Plate boundaries are locations on Earth where portions of the lithosphere interact as they move past each other. What is the difference between the epicenter and the hypocenter of an earthquake? The epicenter is the surface location of an earthquake and is located above the hypocenter. Which of the following terms are types of seismic waves?
Where does the epicenter of an earthquake occur?
An earthquake occurs after strain has built up in the rocks. AND An earthquake originates at the focus. Which of the following responses best describes the epicenter of an earthquake? The point on Earth’s surface directly above the focus of an earthquake.
Why are lithospheric plates able to move on the surface of Earth?
Which of the following responses best describes why the lithospheric plates are able to move around on the surface of Earth? Because the asthenosphere is composed of weak, hot, and dense rock, the cold, rigid, less dense lithospheric plates are capable of moving on it.
