What are the three main cases of corrosion?
There are 3 types of weathering Physical Weathering which is split into two parts a.Freeze-thaw-as water enters cracks and holes it freezes and expands dueing for the rock to form cracks and breaking of the rock bunion skin (Exfoliation)-As the rock heats up and expands by day, and cools and contracts by night, stress is often exerted on the outer layers. The stress causes the peeling off the outer layers of rock in thin sheets. 2. Biological weathering- the roots and animals burrow into rocks which causes them to break. 3. Chemical weathering- mineral dissolving in the water makes the water acidic which then eats away the rock and sometimes causes holes.
What are the layers of computer system and types of layers?
following are the different layers of computer1:APPLICATION PROGRAMS/USER2:UTILITY3:O.S4.HARDWARE
What are the advantages of tunable laser diodes?
UV lasers are good for analyizing top surface layers. It has a penetration depth of only a few nanometers, making it incredibly sensitive, even to very thin layers.
How does plywood get its strength?
From multiple layers of veneer glued together.
Which layers of the OSI model are involved in data encapsulation?
none
Why does rust decrease the strength of an iron bar?
The reason for this is because rust is weaker than iron and decreases strength. Iron rust flakes off and has holes in it that allow water and air to further corrode deeper layers of iron (like a pile of potato chips). Aluminium, stainless steel and other metals form a complete continuous layer and prevent further corrosion. It is not because of reduced surface area if anything the surface area is increased (especially with iron)AnswerI believe its because the overall surface area of the bar is decreased, hence the structural integrity of the bar is compromised. Strangely enough, when aluminum rusts the aluminum oxide on the surface of the metal increases resistance to further corrosion without reducing the surface area. love Tim xxx
Is the rocks layers near the surface of earth younger than rock layers further from the surface?
Yes.
Where is the crust located in the earths layers?
The surface.
Earth's layers can be defined by their chemical composition From surface to center what are these layers?
Crust, mantle, core
Sudden movements of rock layers beneath the surface cause vibration called?
what are movement of rock layers
Why use hard fat for rubbing in?
To obtain a flaky pastry. The hard fat (butter or lard) does not melt into the flour but creates many layers of fat separated by flour. These layers become flakes when the pastry is baked.
How does stress changes Earth's Surface?
stress changes the earth's surface by the way it looks and the layers.
How do atmospheric layers differ?
The five layers of the atmosphere have different atmospheric temperature that occurs with increasing altitude. The layers also thin out with height from the surface.
What is the purpose of the folded layers of membrane?
To increase the surface area.
Is layers of rock near the surface are the oldest rocks?
false
Does aluminum foil corrode if left outside?
Aluminium does corrode. The difference between the corrosion of aluminium and the corrosion of iron (rust), is that aluminium corrosion is galvanic- the oxidised layer that forms acts as a very thin protective barrier to the aluminium beneath it in a process called galvanization, impeding the corrosion process. In comparison, iron oxide does not seal the metal beneath it, and successive layers are exposed and oxidised in turn.
How do cichlid fish reproduce?
They are egg layers and will lay their eggs on a smooth surface surface inside the tank.
