Absolute plate motion describes the motion of one plate relative to a fixed reference system. 28 List and explain the evidence used to support the plate tectonics theory.
4 5 Relative Motion In One And Two Dimensions University Physics Volume 1
Now I give you an equation which helps you to find relative velocities of the objects.
. Scientists first started using. When we describe motion we need to know two important factors. In advance mark locations of ring stands such that all three strings meet in one location Launch the PowerPoint presentation Measuring plate motion with GPS.
Absolute plate motion describes the motion of one plate relative to a fixed reference system. It may be further divided into kinematics the study of motion without Motion Motion A written or oral application. Plate motion is relative to a reference frame.
Present relative motion of Pacific plate past North America is 78my. Measuring the motion of plates relative to each other is a key challenge in understanding plate tectonics. The force of gravity was measured by noting how much the wire twisted.
Calculate a vector from the time series plot that represents the motion of a GPS station. Two versions of Euler poles. The motion of a point on one tectonic plate relative to another plate can be described by the relative velocity vector v.
The velocity v has magnitude and direction and is given by the cross product of the angular velocity vector ω and the plate rotation vector r. 210 Describe platemantle convection and explain two of the primary driving forces of plate motion. Scientists know that these plates move from two different lines of evidencegeodetic and geologicwhich allow them to trace their movements back in geologic time.
Where are areas that. 1 Direction 2 Distance We measure the _____ of the path that an object took. Measurement from your initial position to your final position is distance traveled and the measurement of the total length of your path from the starting position to the final position is displacement.
Plate motion can be described by a pole of rotation and an angular velocity about this pole. Seismometers can also detect subtle motion and capture relatively small movements at high frequencies. 1 Data collected from the sea floor can establish motion of the plates fossils rocks etc 2 GPS satellites 210 Refer to Figure 234 and determine which three plates appear to exhibit the highest rates of.
Up to 10 cash back Relative plate motion describes the motion of one tectonic plate relative to another. Lets say we walked around the block with a string. Scientists measure plate tectonics using GPS satellites and they use computer models that simulate the motions of Earths tectonic plates to try to predict future plate movements.
Sketch a few vectors that indicate plates spreading a divergent boundary. Both plates have a northward component on motion but Africa also has a component to the east and North America has a component to the west. VrelaltiveVobject-Vobserver Example What is the velocity of the B with respect to A.
The distance would be the total number of feet yards etc. Find areas with high rates of motion - where are these areas. Relative Motion of Two Plates.
By using GPS satellites in tandem with GPS receivers on the ground scientists measure the rate of movement of the Earths crust. Introducing GPS to study tectonic plates as they move twist and crumple. Describe the motion of a GPS station by interpreting time series plots.
Over the past ten or fifteen years global positioning system satellite data has become an invaluable tool for measuring plate motion and strain accumulation across faults. And Changing the reference frame changes the perspective of plate motion. Of string that followed us.
29 Describe two methods researchers use to measure relative plate motion. RELATIVE PLATE VELOCITIES are described by instantaneous poles or Euler vectors or angular velocity vectors For each plate pair need a pole position and b angular rate equivalent to vector direction thru center of earth and vector length Example. Create time series plots of GPS station data.
Rates of relative plate motion are recorded by arrays of linear geomagnetic anomalies where earths magnetic field is greater or less than expected which lie parallel to loci of seafloor spreading within ocean basins. The sudden movements on faults that produce earthquakes are recorded by seismometers but we know that all the plates on the surface of the Earth are in constant motion. Use distance to describe the shortest path between starting and ending points and use displacement to describe the total path between starting and ending points.
V²BAV²BV²A V²BA3²4² V²BA25 VBA5ms to the southeast Example Find the velocity of L with respect to K and M. Geodetic Plate Motion Geodesy the science of measuring the Earths shape and positions on it allows the measurement of plate motion directly using GPS the Global Positioning System. This is the motion of the African and North American plates in the NNR-NUVEL-1A plate model along part of the Mid Atlantic Ridge.
210 Describe two methods researchers use to measure relative plate motion. Scientists have long used seismometers to detect vibrations caused by the plates motion especially during large events like earthquakes. The second approach was similar to the first except that the plate was.
Motion Sickness Definition Motion sickness is uncomfortable dizziness nausea and vomiting that people experience when their sense of balance and equilibrium is d Dynamics dynamics dynamics branch of mechanics that deals with the motion of objects. Where else in the world do we see seafloor spreading. Draw conclusions about plate motion in the Pacific Northwest by comparing the motion of GPS stations.
The equation looks like this where the x means cross-product. Relative plate motion describes the motion of one tectonic plate relative to another. To graphically find the resultant.
A Scientific Revolution Unfolds. Two steel balls provided a gravitational attraction.
