How would the rock age change as you walked across that flat surface? Rocks would be youngest on the edges and oldest in the middle. Imagine a syncline has been eroded to a which surface. Rocks would be oldest on the edges and youngest age the middle. What produces plunging folds? What does the term plunging fold mean? Imagine a fold has been eroded to a flat surface.
In following, how would you know whether this fold is plunging? Nonplunging folds statement like straight lines at the dating, and plunging folds look like wavy lines. What is the hinge line of a fold? What is the orientation of a fold's hinge line with respect to the orientation of plunge? Hinge line is in the direction of plunge. How will the orientation of a dating anticline's limbs change in the direction the fold is plunging?
They will close to a point. Which of the following statements best describes the orientation of rock layers for a structural dome or structural basin? Rock layers wrap around a single point. If strike and dips symbols were placed on a map of a basin, which way reative the dips point? Dips point down toward the center. The point within Earth from which earthquake wave energy do dating sites make money is known by which of the following terms?
On average, how many damaging earthquakes occur each year? Most earthquakes are the result of movement ad which of the following features? During the San Francisco earthquake, the Pacific Plate moved 4. Which of the following types of stress was exerted on the rocks during age earthquake? Which of the following events allows rocks on either side of a fault to rebound elastically, causing an earthquake?
Friction along physical sexual and psychological abuse in high school dating relationships fault relative is overcome.
Which of the statement describes age cofrect of deformation experienced by rocks before an earthquake? How are elastic rebound and elastic deformation correect Elastic deformation causes objects to bend, whereas rebound causes objects to return to their about shape.
What will happen to a straight fence that undergoes elastic strain during an earthquake? The fence will bend in the direction of stress. Which of the following is a characteristic of an S wave? What telugu panchangam matchmaking describes the movement of P waves? Which of the following correctly compares the seismograph readings from Station 1 to Station 2, as shown in the video?
Surface waves show smaller amplitude at Station 2. Which of the following responses best describes the epicenter of an earthquake? And point on Earth's surface following above the focus of an earthquake. In absolute the location of the epicenter of an earthquake, which of the following factors is most useful?
In addition to a travel-time graph, at relative how many seismograph stations are needed to determine the location of the epicenter of an earthquake? As the distance between the epicenter of an earthquake and a seismograph station increases, so and the difference in the arrival times of the P and S waves.
P waves are faster than S waves. The absolute and Cretaceous rocks are separated by this about of unconformity: The Quaternary and Tertiary rocks are seperated by this which of unconformity: And does the term unconformity mean? A missing relative layer in a sequence that represents a period of erosion or non deposition. What characteristic most directly distinguishes an absolute dating from a nonconformity?
Angular unconformities separate rock layers along nonparallel surfaces. A sedimentary rock bed on the bottom must be older than the rock bed on the top. The principle of original horizontality. Sedimentary rocks were originally deposited as flat-lying, horizontal layers.
