How do you Calculation the rate of sea floor spreading examples?
The rate of sea floor spreading is calculated by measuring the distance between magnetic stripes on the sea floor, which are formed by the alternating polarity of Earth's magnetic field. By knowing the age of the sea floor rocks at different distances from a mid-ocean ridge, scientists can determine the spreading rate. For example, if the rocks at a certain distance from the ridge are 1 million years old, and the distance is 100 km, the spreading rate would be 10 cm/year.
What percent of time since earth was formed have humans lived on earth?
When calculated according to the 4.6 billion years since earth was formed humans have live in it 0.09 percent of the time.
How do you calculate the rate of seafloor spreading?
rate of spreading for stripe = width of stripe / time duration If a magnetic strips is 60 km wide and formed over 2 million years, then the rate at which spreading formed the was 30 km/m.y. The rate is equivalent to 3 cm/year. Spreading added an equal width of oceanic crust to a plate on the other side of the mid-ocean ridge, so the total rate of spreading across the ridge was 60 km/m.y. (6 cm/year), a typical rate of seafloor spreading.
How far away is a rainbow when it is formed?
It is hard to judge how far away a rain cloud is especially if it's moving. The rainbow's distance extends from the nearest to the farthest raindrops that contribute any part of the colored light. The closest of these raindrops may be miles away. In the case of water spray from a lawn sprinkler in which a rainbow appears, you can reach right in and "touch it"....or so it seems. Many questions are unique to one's cultural history. Hoped This Helped.
How does the age of seafloor bedrock vary with distance from a mid-ocean ridge?
The age of seafloor bedrock increases with distance from a mid-ocean ridge. At the ridge, the bedrock is young, as it is continuously being formed by volcanic activity. As it moves away from the ridge through the process of seafloor spreading, it cools and ages over time.
What was the distance between the Earth and the stars before the Earth was formed?
It is the distance of the extension of what your eyes can see. If the earth wasn't formed, there can be no possibility of measuring distances to or from it.
What expression gives the distance between two points?
The distance between two points in a Cartesian coordinate system can be calculated using the distance formula: ( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ). Here, ((x_1, y_1)) and ((x_2, y_2)) are the coordinates of the two points. This formula is derived from the Pythagorean theorem, where the distance represents the hypotenuse of a right triangle formed by the differences in the x and y coordinates.
What two factor determines the types of image formed by a lens?
The distance of object and the distance of image.
How do you calculate the position of the image formed?
To calculate the position of the image formed by a lens or mirror, you need to use the thin lens or mirror formula: 1/f = 1/do + 1/di, where f is the focal length of the lens or mirror, do is the object distance, and di is the image distance. Once you have the values for the focal length and object distance, you can solve for the image distance to determine the position of the image formed.
How does the image distance compare to the object distance?
The image distance is the distance from the lens to where the image is formed, while the object distance is the distance from the lens to the object. In general, for real images, the image distance is different from the object distance. For virtual images, the image distance is negative and the object distance is positive.
How do you find how far an image is formed from the lens if you have the distance from the lens to the object and the focal length how do you solve for distance from image that is formed?
Here's the equation you want. It's called the "Lensmaker's Formula".1/i + 1/o = 1/fi = image distance from the lenso = object distance from the lensf = focal length of the lens
How to calculate x of a lens knowing only the focal length which is the distance from the lens to the image of sun formed by it correct me if I'm wrong?
1/(focal length) = 1/(distance of object) + 1/(distance of image) is the formula for calculating x of a lens knowing only the focal length which is the distance from the lens to the image of sun formed by it.
What are the characteristics of image formed by plain mirror?
same size, upright, and same distance
What a solid formed by all points in space that are the same distance from a fixed point?
A sphere
What is true about the arcs formed by parallel lines?
They remain equal distance from one another
What is the distance from the vertex of a right cone or right pyramid to a point on the edge of the base?
The distance from the vertex of a right cone or right pyramid to a point on the edge of the base can be determined using the Pythagorean theorem. This distance is the hypotenuse of a right triangle formed by the height of the cone or pyramid, the radius of the base (for a cone) or the apothem (for a pyramid), and the slant height as the hypotenuse. For a cone, the distance is calculated as (d = \sqrt{h^2 + r^2}), where (h) is the height and (r) is the radius. For a pyramid, the formula would involve the height and the apothem of the base.
What is the object image distance relationship for a flat mirror?
when dealing with a flat mirror object-distance and image-distance should be equal.
