The plates are moving approximately 1 centimeter 05 inches to 15 centimeters 6 inches per year in different directions. The mantle is the layer of the Earth located directly under the crust.

I Have Used This Webquest As An Introduction To Plate Tectonics With My 6th Grade Classes It Can Also Be Used As A Review Plate Tectonics Webquest Science Web

Human fingernails grow at the low end of the rates of plate motion a few cmyr.

Determining how fast some crustal plates move worksheet answers. Plate Tectonics Summary The Earth is made up of 3 main layers core mantle crust On the surface of the Earth are tectonic plates that slowly move around the globe Plates are made of crust and upper mantle lithosphere There are 2 types of plate There are 3 types of plate boundaries Volcanoes and Earthquakes are closely. This hot spot was created in the middle of the pacific plate. But by studying rock formations along boundaries scientists can figure out how fast each plate has been moving on average over a given time period.

This may seem rather rather slow to us but is very fast on the geological time scale. Answer key Keep in mind the measurements wont be exact and students answers may vary but the. This map shows the major tectonic plates that make up the Earths crust and the directions in which they are moving.

Speed of crustal movement cmyr Distance between the two islands cm Difference in approximate ages of the two islands yrs. When the edges of plates meet four things can happen. When the crustal plate moves it vibrates the earths crust and its plates.

Describe the structure of a hotspot like the one that created the Hawaiian Islands. Students should fill out the second table on the Data Worksheet to determine how far the Pacific Plate has moved in 17 years. Most scientists believe that the Earths crust is broken into pieces much like the cracked shell of a hard-cooked egg.

____ model and explain how convection currents in the mantle cause the movement of tectonic plates. Individual parts of interacting plates can move more than several feet during earthquakes. Actual distance Measured Distancecolumn Bcm x 43 kmcm 3.

These plates fit together like a puzzle but theyre not stuck in one place. These pieces are called crustal plates and are thought to be moving across the mantle. Using the map scale determine the actual distance to the nearest 01 KmRecord in Table 2 Column C.

Plate tectonics is the unifying theory of geology. I would consider it fluctuating because the distance between the two islands and the difference in approximate ages of two islands was always different. Map adapted from NOAA.

Using the following formula calculate the approximate speed at which the crustal plate was moving between the times that each of the islands formed. ____ use a boundary map to explain various plate interactions around the world. Crustal plate margins _____ b.

Convert the actual distance in kilometers from each island volcanic peak to the Kilauea peak to centimeters and record in Column D on Table 2. ____ describe the movement and interaction of the 3 primary types of plate boundaries convergent divergent transform. Moving across the mantle.

Plates typically move about 1-15 cmyear which is equivalent to 10-150 kmMa kilometers per million years. The flow of the mantle causes tectonic plates to move in different directions. Plate Tectonics Worksheet 2 L1 4 3.

Determining How Fast Some Crustal Plates Move. The mantle is the layer of the earth located directly under the crust. Determining How Fast Plates Move.

Describe your answer in detail. Finally students convert their answers from kmyr to cmyr by multiplying your average by 100000. Record your data in the chart provided.

The mantle is the layer of the Earth located directly under the crust. 5 Using the following formula calculate the approximate speed at which the crustal plate was moving over the hot spot during the times that each of the following pairs of islands formed. Distance cm Distance.

When the crust and plates are forced to move it can result in volcanic action. You know that the Earths crustal plates are always moving but how fast. This theory explains how crustal plates move around the surface of the earth and it allows geologists to find explanations for geologic events such as earthquakes and volcanoes as well as the many other processes that form transform and destroy rocks.

Most scientists believe that the earths crust is broken into pieces much like the cracked shell of a hard-cooked egg. Divergent margins and continental spreading centers. The crust of the earth is.

These pieces are called crustal plates and are thought to. Determining How Fast Some Crustal Plates Move Most scientists believe that the Earths crust is broken into pieces much like the cracked shell of a hard-cooked egg. They are floating on Earths mantle a really thick layer of hot flowing rock.

Each of Earths plates can move at a different speed and these speeds can change over geological time. Interior of a crustal plate _____ Answer the following questions about Plate Tectonic Processes using the diagrams with the map. New crust forms at plate margins as _____ rises creating ridges under.

The average rate of movement of tectonic plates per year is roughly one to two inches. These pieces are called crustal plates and are thought to be moving across the mantle.
