What are found on the outer surfaces of stromatolites?
Microbial mats and sediment layers are typically found on the outer surfaces of stromatolites. These structures are formed by the trapping and binding of sediment particles by microbial communities, resulting in layered structures visible on the surface.
What is the cause of Newton's rings?
When a plano-convex lens with its convex surface is placed on a plane glass sheet, an air film of gradually increasing thickness outward is formed between the lens and the sheet. The thickness of film at the point of contact is zero. If monochromatic light is allowed to fall normally on the lens, and the film is viewed in reflected light, alternate bright and dark concentric rings are seen around the point of contact. These rings were first discovered by Newton, that's why they are called NEWTON'S RINGS .experimental setupPattern of Newton's RingWHY NEWTON'S RINGS ARE FORMEDNewton's rings are formed due to interference between the light waves reflected from the top and bottom surfaces of the air film formed between the lens and glass sheet. EXPLANATIONThe phenomenon of the formation of theNewton's rings can be explained on the basis of wave theory of light.An air film of varying thickness is formed between the lens and the glass sheet.When a light ray is incident on the upper surface of the lens, it is reflected as well as refracted.When the refracted ray strikes the glass sheet, it undergo a phase change of 180O on reflection.Interference occurs between the two waves which interfere constructively if path difference between them is (m+1/2)land destructively if path difference between them is mlproducing alternate bright and dark rings.
What is the edge formed by two surfaces meeting each other called?
The edge formed by two surfaces meeting each other is called a "corner" or a "boundary."
What rock is formed when magama cools at the earth's surface?
Igneous rock, such as basalt or rhyolite, is formed when magma cools at the Earth's surface.
Why are metamorphic rocks not common on Earth's surface?
They are formed under the earth's surface.
A small angled surface formed between two surfaces?
a square

I may be the upper or lower half of any oblate or prolate spheroid.You'll never know.bwahahaha
Where are the rings formed in newton's ring experiment?
The rings are formed due to interference between two surfaces – a convex lens and a flat glass plate placed in contact. The rings are most prominent at the point of contact between the two surfaces.
How is friction formed?
Scientists are not completely sure what causes friction; however, it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.
Why do suction cup stick to wet surfaces better than dry surfaces?
Suction cups stick better to wet surfaces because the water fills the small gaps and imperfections in the surface, creating a stronger seal and reducing air pockets. This increased contact area between the suction cup and the surface results in better suction and adhesion. On dry surfaces, air pockets can form, reducing the effectiveness of the suction cup.
Why are mirror images perfect?
No ! The images formed by a mirror are not perfect !!The finest images are those formed by a right angled PRISM . However the rays from the object need to fall perpendicularly on prism's surface . Thus for convenience mirrors are used .
Can shadows be formed on shiny surfaces?
Yes, shadows can be formed on shiny surfaces. Shiny surfaces reflect light, but shadows occur due to the obstruction of light. The shadow may appear lighter or distorted on a shiny surface depending on the angle of light reflection.
Which types of triangles can be formed by taking the cross-section of a cube?
Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
How microwelds impact friction?
Microwelds are tiny metallurgical bonds formed between contacting surfaces under high pressure and temperature. These bonds can increase friction by creating adhesion between the surfaces, leading to stiction. However, in some cases, microwelds can also reduce friction by providing contact points that distribute load and reduce surface roughness.
What is formed when bumps from two surfaces come into contact?
When bumps from two surfaces come into contact, they can create friction, which is a force that resists the motion between the two surfaces. This friction can lead to heat generation and wear on the surfaces.
What Reflection from a smooth surface?
When light hits a smooth surface, it reflects in a predictable manner called specular reflection. This type of reflection results in a clear and well-defined image being formed. Examples of smooth surfaces that exhibit specular reflection include mirrors and still water surfaces.
