What layer holds the fewest gas molecules and air particles?
The exosphere is the outermost layer of the Earth's atmosphere and holds the fewest gas molecules and air particles. This layer extends from about 500 km above the Earth's surface to the edge of space.
In what part of the atmosphere does solar particles hit atoms and cause them to glow?
In the very highest layer of the atmosphere, the ionosphere, solar particles collide with oxygen and nitrogen atoms and green, blue and red light is given off.This light is the http://wiki.answers.com/FAQ/7810
What causes a boundary layer to develop in fluids?
A boundary layer develops in fluids due to the friction between the fluid and a solid surface. This friction slows down the fluid velocity near the surface, leading to the formation of a boundary layer where the flow transitions from the no-slip condition at the surface to a freer-flowing condition away from it.
Why do slippery fluids such as oil reduce sliding friction?
We can reduce friction by oiling ("lubricating") the surfaces. This means that the surfaces no longer rub directly on each other, but slide past on a layer of oil. It's now much easier to move them.
Extra layer of epidermis on feet is called what?
The extra layer of epidermis on the feet is called the stratum lucidum, which is a translucent layer of dead skin cells that helps to protect the skin from friction and pressure.
Why do large particles in a rock layer cause less friction than small particles?
Large particles have less total surface area, so caused less friction then the smaller particles do
How does lubicus help to reduce friction?
Lubricants reduce friction by various means. Here are some:They form a layer between surfaces that are moving with respect to each other that keeps those surface from contacting each other. The lubricant keeps the surfaces apart.The lubricant washes away particles that might cause friction between the surfaces. It acts as as cleanser.Some lubricants harden the surfaces of the parts they are lubricating to make them less subject to wear.
Why is friction low on snow?
Friction is low on snow because the structure of snowflakes creates a layer of air between the object and the snow, reducing direct contact and friction. Additionally, snow is often made up of small, loose particles that can easily move past each other, further reducing friction.
Why do slippry fluids reduce sliding friction?
Because in a liquid, particles have greater kinetic energy than particles in a solid. So, there are weaker forces of attraction in the liquid between particles. As a result, particles can move past each other with ease. Fluids like the 'slippery' fluids are lubricants, and they come into contact as opposed to the surfaces of the solids.
What do lubricants do to friction by replacing sliding friction with fluid friction?
Lubricants reduce friction by replacing sliding friction with fluid friction.
What layer of the atmosphere do particles of air escape into space?
The layer of the atmosphere that releases particles of air into space is the exosphere.
Lubricants do what to friction by replacing sliding friction with fluid friction?
the correction option is true :)
What layer has charged particles?
The Answer is...... IONOSPHERE
What layer are cool particles pulled down by gravity?
Cool particles are typically pulled down by gravity at the troposphere layer. The troposphere is the lowest layer of the Earth's atmosphere where weather phenomena occur, and gravity causes particles to settle towards the Earth's surface within this layer.
What prevents friction between the layer of the pericardium?
pericardial fluid
How can wind cause erosion?
Wind is very energetic and will either drag particles off of a layer of rock or push debris into the rock and break it down.
What Lubricants reduce friction by replacing sliding friction with fluid friction?
Viscous lubricants, such as oils and greases, reduce friction by creating a fluid layer between moving surfaces. This fluid layer separates the surfaces, allowing them to slide past each other with less resistance. The viscosity of the lubricant determines the effectiveness of this fluid friction.
