Plate Motion and Direction Analysis

The video tutorial explains how to calculate the rate and direction of plate motion using the Hawaiian plate as an example. It covers the steps to find the rate by dividing the distance between two locations by the time difference. The tutorial also demonstrates converting the rate from kilometers per million years to centimeters per year. Additionally, it explains how to determine the direction of plate motion by drawing an arrow from the youngest to the oldest point. Finally, it provides instructions for calculating the rate and direction from 1.6 million years to the present.

What is the primary goal when calculating plate motion on the Hawaiian plate?

• To determine the age of the islands

• To measure the height of the islands

• To find the rate and direction of plate motion

• To calculate the temperature of lava flows

What tool is used to measure the distance between two locations on the Hawaiian plate?

• A ruler

• A compass

• A protractor

• An envelope

How is the rate of plate motion initially calculated?

• By subtracting time from distance

• By adding distance and time

• By dividing distance by time

• By multiplying distance by time

What is the rate of plate motion in centimeters per year after conversion?

• 95.2 cm per year

• 19.5 cm per year

• 0.95 cm per year

• 9.5 cm per year

How is the direction of plate motion determined?

• By drawing an arrow from the oldest to the youngest point

• By calculating the rate of motion

• By measuring the distance between two points

• By drawing an arrow from the youngest to the oldest point

In which direction is the Hawaiian plate moving?

• Southwest

• Northwest

• Northeast

• Southeast

What is the significance of the hot spot in determining plate motion?

• It remains stationary

• It changes direction frequently

• It moves with the plate

• It is irrelevant to plate motion

What is the next step after calculating the rate of plate motion from 1.6 million years to the present?

• Measure the temperature of the plate

• Convert the rate to kilometers per year

• Draw an arrow to determine direction

• Recalculate the distance

How does the direction of plate motion change from 1.6 million years to the present?

• It reverses completely

• It becomes unpredictable

• It shifts slightly

• It remains the same

What is the final step in determining the rate and direction of plate motion?

• Calculating the average temperature

• Drawing a map of the islands

• Writing down the rate and direction

• Measuring the height of the islands
