What is a spreading rate?
The rate at which seafloor is produced is called the spreading rate. Because seafloor is produced to both sides of the midocean ridges, the full spreading rate is about twice that to one side, or the half-spreading rate.
What is the spreading rate 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.
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 you calculate spreading rate in paint?
- Spreading Rate (m2/litre) =
- % Volume Solids x 10.
- =
- 71 x 10 = 5.7 m2/litre ✓
- DFT Required.
- 125.
What is the spreading rate in cm yr?
1 cm/yr
spreading ridge axis we can estimate the spreading rate. Spreading Rate = 1 cm/yr Typical spreading rates range from 1 – 10 cm/yr Distance of the 7th normal stripe (green) is about 40 km from the ridge crest. The age is about 4 million years.
How do you calculate spread rate in paint?
How do you calculate movement in centimeters per year?
Use the formula (island distance from hotspot ÷ island age) to calculate the rate of movement for 1. each island in the chart, then multiply by . 1 to convert from kilometers per million years to centimeters per year.
How do you calculate half spread 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.
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 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.
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.
How to calculate the spread of the sea floor?
Calculating Sea Floor Spreading. Rate of Spreading = distance the sea floor moved / length of time. or R = d/t. Generally expressed as cm/yr. Source: http://www.geo.cornell.edu/geology/classes/Geo101/graphics/ocean_crust_age.gif. 1 km = 1000 m. 1 m = 100 cm. so 1 km = 100,000 cm or 10 5 cm. 1.
When do you use the word spread in finance?
Yield spread The word “spread” is also used when talking about debt securities, such as bonds or CDs. The calculation for a yield spread is essentially the same as for a bid-ask spread – simply subtract one yield from the other. For example,…
How is the spreading rate of a coating determined?
Theoretical Spreading Rate / Coverage. 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 a yield spread expressed in basis points?
Yield spreads are often expressed in basis points, and a 1% difference in yield is equal to 100 basis points. So, the yield spread between two bonds — one paying 5% and one paying 4.8% could be stated as either 0.2% or 20 basis points.
