# How To Calculate Spreading Rate

## How To Calculate Spreading Rate?

It is possible to calculate the spreading rate of one side of a mid-ocean ridge by dividing distance by time (Distance/Time = Rate). This is called a half-spreading rate. Multiply it by 2 to get the full spreading rate for both sides of the ridge.Mar 23 2003

## What is a spreading rate?

The area of surface covered per coat of paint at a specified dry film thickness per unit volume of coating material. Spreading rate generally is indicated by square feet covered per gallon or square meter covered per liter of paint.

## What is the rate of seafloor spreading?

It spreads about 6-16 centimeters (3-6 inches) every year. There is not an ocean trench at the East Pacific Rise because the seafloor spreading is too rapid for one to develop! The newest thinnest crust on Earth is located near the center of mid-ocean ridge—the actual site of seafloor spreading.

## What is the rate of spreading rate in cm per year?

These age data also allow the rate of seafloor spreading to be determined and they show that rates vary from about 0.1 cm (0.04 inch) per year to 17 cm (6.7 inches) per year.

## What is the spreading rate for each ridge?

Spreading rates determine if the ridge is fast intermediate or slow. As a general rule fast ridges have spreading (opening) rates of more than 90 mm/year. Intermediate ridges have a spreading rate of 40–90 mm/year while slow spreading ridges have a rate less than 40 mm/year.

## What is the spreading rate of oceanic ridges per year?

Global spreading rates range from 10 mm (0.4 inch) per year or less up to 160 mm (6.3 inches) per year. Oceanic ridges can be classified as slow (up to 50 mm [about 2 inches] per year intermediate (up to 90 mm (about 3.5 inches) per year and fast (up to 160 mm per year).

## What formula do you use to calculate the rate of movement in this lab?

The equation for speed is simple: distance divided by time. You take the distance traveled (for example 3 meters) and divide it by the time (three seconds) to get the speed (one meter per second). But what practical considerations do you have to make to measure an object’s speed in real life?

## What is the average spreading rate of the Atlantic Ocean in cm yr?

around 2 cm/yr

(18km/My) * (0.621mi/km) * (5280ft/mi) * (12in/ft) * (1 My/1 000 000yr) = 0.7in/yr Note: The average spreading rate in the Atlantic is around 2 cm/yr. Student answers however may vary here somewhat depending on the sea floor strip they use.

## How much does the Eurasian plate move a year?

The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year.

## What is the approximate rate of sea floor spreading in the South Atlantic?

Because of seafloor spreading and the movement of the ocean floor and of the continents outward from the ridge the Atlantic Basin is widening at an estimated rate of 1 to 10 cm (0.5 to 4 inches) a year.

## What is the average spreading rate of paint?

Paint Coverage Rates
ES 27 40 – 50 sq metres per 5.0 Litres.
EP 27 40 – 50 sq metres per 5.0 Litres.
A 30 40 sq metres per 5.0 Litres per coat @ 25 microns dry film thickness.
AG 30 40 sq metres per 5.0 Litres per coat @ 25 microns dry film thickness.

## What is spread rate painting?

The Theoretical spreading rate or coverage of a coating is a function of the volume solids. The volume solids is the percentage of the coating consisting of binder and pigments which remain on the substrate forming the final paint film after the volatile components or solvents evaporate.

## How is paint area coverage calculated?

To estimate the amount of paint you need in order to cover the walls of a room add together the length of all the walls and then multiply the number by the height of the room from floor to ceiling. The number you get is the room’s square footage.

## What is the spreading rate along the boundary?

Spreading rates range from approximately 10–200 mm/yr. Slow-spreading ridges such as the Mid-Atlantic Ridge have spread much less far (showing a steeper profile) than faster ridges such as the East Pacific Rise (gentle profile) for the same amount of time and cooling and consequent bathymetric deepening.

## How do geologists calculate rates of seafloor spreading?

To calculate the rate of the spreading you need to use the following formula: the distance the sea floor moved divided by the length of time. This is an important concept for people in the earth sciences field. To complete these calculations you will need maps showing the Earth’s crust.

## What is seafloor spreading theory?

seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid-ocean ridge system and spreads out laterally away from them. … The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960.

## How does the rate of seafloor spreading affect sea level?

The increased rate of seafloor spreading caused sea level to rise. Increasing the rate of seafloor spreading inflates the ridge. Hot young lithosphere is forming and moving away from the ridge at a faster rate and moves a greater distance from the ridge before it cools and contracts. … So sea level rises.

## What is fractionated plateau?

Fractioned plateau is the longest mountain chain on the earth’s surface which is submerged u.

## How seafloor spreading occurs in the mid-ocean ridge?

Seafloor spreading is the process by which new oceanic lithosphere forms at mid-ocean ridges. As tectonic plates move away from each other magma rises from Earth’s interior. It then cools and solidifies in the center of the ridge. The rising magma pushes up between the plates and drives them further apart.

## How do we calculate distance?

To solve for distance use the formula for distance d = st or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s r = s = d/t.

## How do you calculate speed distance and time?

The formula can be rearranged in three ways:
1. speed = distance ÷ time.
2. distance = speed × time.
3. time = distance ÷ speed.

## What is the average rate of seafloor spreading in modern oceans?

What is the average rate of seafloor spreading in modern oceans? 5 centimeters (2 inches)per year.

## How many kilometers has the left side of the Pacific Basin spread?

approximately 37 km 3. Pacific: approximately 160 km North Atlantic: approximately 74 km South Atlantic: approximately 78 km 4. The South Atlantic Ocean basin’s spreading rate is 3.9 cm/yr.

## How do I calculate cm a year?

There are 100 000 cm in one km and there are 1 000 000 years in one Ma. Unit conversion analysis shows that to make it quick and simple you just need to multiply km/Ma by 0.1 (one tenth) to convert to cm/yr.

## What is the rate of movement?

1 a quantity or amount considered in relation to or measured against another quantity or amount. a rate of 70 miles an hour.

## How much does a continent move each year?

The North American and Eurasian tectonic plates for example are separated by the Mid-Atlantic Ridge. The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. Rift valleys are sites where a continental landmass is ripping itself apart.

## At what speed and direction is the Eurasian plate moving?

## How do scientists measure the rate of plate tectonics?

The Global Positioning System Scientists use a system of satellites called the global positioning system (GPS) to measure the rate of tectonic plate movement.

## How do you calculate rate in geology?

Calculate the rate using ΔX and Δt. so to calculate the rate you need to divide ΔX by Δt. This is your answer that the the rate of retreat is 12.7 meters per year.

## Is the rate of movement of the Pacific plate constant?

The pacific plate rotates around a point south of Australia. Around Hawaii the plate is moving at about 7 cm/year or about as fast as finger mails grow. The evidence for this motion is pretty convincing: earthquakes: earthquakes occur on the boundaries of the plates as they rub past each other.
