Isochron Map Of Ocean Floor Crust Worksheet Answer Key - The correct answer for each question is indicated by a. The oldest sections of seafloor? Refer to the plate tectonics lab for the information you need to complete this worksheet. The theory of seafloor spreading indicates that the tectonic plates slowly move away from each other.

Digital Agegrid Of The Ocean Floor/Digital Isochrons Of The World's Ocean Floor/A Global

When completing the worksheet you will interpret a map of magnetic patterns on the ocean floor. The age at each grid node was determined by linear interpolation between adjacent isochrons in the direction of spreading. Most found along seafloor in rift valley.

A Field With The Same Orientation As Today's Field Is Said To Have:

An isochron is an imaginary line on a map that shows points that have the same age—that is, they formed at the same time. The map was compiled from dozens of magnetic profiles like those in part i, measured from oceanographic research ships that traversed the area. What color is used to represent the youngest sections of seafloor?

Seafloor Spreading Isochron Ocean Floor Crust 1.

In addition they were able to easily create isochron maps of the ocean floor using this technology. Earth's ___________has changed over time. When completing the worksheet you will analyze and.

The Process Of Seafloor Spreading In Order.

How did researchers determine the ages of the seafloor crust? What does each band of color on the seafloor represent? Then more molten rock that formed before, pushing it ocean floor.

Use The Ruler Tool To Determine How Far These Points Have Moved Apart (In Km).

On a map, an isochron is a line that connects locations with the same age. Were first developed using data from oceanic rocks and sediment. Refer to figure 17.13 for the isochron map of the ocean floor.

The Age At Each Grid Node Was Determined By Linear Interpolation Between Adjacent Isochrons In The Direction Of Spreading.

Let us first define key terms: All calculations and graphs that you perform in this class are expected to meet the basic scientific standards explained in. Isochron maps indicate the age of the seafloor on the ocean crust.

Explain How The Features Of The Ocean Floor Are Formed.

How old is the ocean crust just off the east coast of the united states? Discuss the directions with students; The study of the history of earth's magnetic field.

Identifying Parts Of The Ocean Floor Bonus Box Answer:

The isochron map determines which areas in the map formed simultaneously by drawing imaginary lines on them. Ages for ocean floor between the oldest identified magnetic anomalies and continental crust were interpolated by estimating the ages of passive continental margin segments from geological data and published plate models. State the features that make up the topography of the ocean floor.

This Unit Depicts The Topography Of The Ocean Floor And Describes How The Features Of The Ocean Floor Are Formed.
