Which is greater 12.12 or 12.9?
12.9 is greater because if count 1 point after decimal so 9 is greater than 1.
Which is greater 1.03 or 0.03?
1.03 is greater then 0.03 because 0.03 doesn't have a 1 in front of the point making 1.03 greater then 0.03
How will knowing the density of a substance help you determine whether an object made from that material will float in water?
If an object is to float in water it must displace a volume of water equal to its weight; knowing the density of the substance that makes up the object allow a calculation to be made of the volume of water that must be displaced so that the object will float. If a substance has a density greater than that of water, it can be made to float by, for example, making it hollow; for example a ship made out of steel can be made to float as it has lots of hollow space inside it which means its effective density is less than that of water. Should the hull be compromised in any way, or by "splashing" over the top, the effective density can increase to the point where it is greater than that of water and the ship will sink. The density of water is not constant as it depends upon its temperature and things (like salt) dissolved in it; it was this change in density that led to loss of shipping and cargo which prompted the invention of the Plimsoll Line which is marked on the side of ships - it shows where the surface of water will be in different types of sea [water] for a given loading (the Line itself marks the maximum safe load). However, for small solid objects made of a substance of a greater density than that of water can still be made to float by using the surface tension of water: a clean sewing needle can be made to float if dropped very gently onto some water* as the force provided by the surface tension is enough to prevent the needle from passing through. If the surface tension is disrupted, for example by agitating the water, or by a drop of washing up liquid, the needle will sink. * If you don't have a steady enough hand: laying the needle on a piece of blotting paper or tissue paper and gently putting the paper on the water will make this easier to achieve - the paper will fairly quickly soak up water and sink away leaving the needle floating on the surface [tension].
Where is the density of the material greater at point b or c?
I'm not sure on this but i would have to say "B" because I think it is closer to the Earths crust. If it is, that is because the crust is the coldest layer of Earth. Usually it is most dense when coldest. that is because particles are closer together than when warmer. (if you would go down into the earths layers it would increase by 1*C until you got to the core) So I would say B, i guess
Is 11.1 greater or less than 11.100?
No, They are the same value Trailing zeros AFTER a decimal point can be ignored.
Where is the density material greater at point b or point c?
the density will be greater at point B because my mommy says
Where is the density material greater at point a or b?
It depends on the material and the location of points a and b.
Where is the temperture of the mantle material greater at point B or point C?
The temperature increases the deeper you go. For earth, the hottest area of the mantle is just before you hit the core. Here it's around 4,000 °C (7,230 °F).
Where is the temperature of the mantle greater point a or point b?
The temperature of the mantle is greater at Point B than Point A. The temperature of the mantle is determined by its depth which is greater at Point B than Point A. The deeper the mantle the hotter and more pressurized it is and so the temperature at Point B will be greater than at Point A.Temperature can also be affected by other factors such as the composition of the mantle and the presence of radioactive elements. In this case since both points are in the same area and have similar composition the temperature will be determined by the depth.To summarize the temperature of the mantle is greater at Point B than Point A because it is deeper and thus more pressurized and hot.
What is a mantle in the earth?
The Earths mantle is the viscous layer between the core and the crust. It is hot because of heat from the core, and part-liquid because it is composed of material with a moderate melting point. This mantle is the source of the volcanic material. Silica is a major component.
When magma forms within the mantle it is most often a result of?
Either the loss of confining pressure causing the melting point of the material to drop below the in-situ temperature or due to the presence of volatiles which enter the mantle where subduction occurs and also lower the melting point of the material.
What causes to the temperature and the density of the material between point b and c?
the heat makes the density less or more dence depending were it is in the earths layers
Is the temperature of the stiffer mantle above or below its mantle point?
is the temperature if the stiffer mantle above or below its melting point
What happens to the temperature and the density of the material between point b and c?
The answer depends on where points b and c are!
What will happen if the density of an object placed in a liquid if the density of the liquid is greater than that of the object?
If the density of the liquid is greater than that of the object, the object will sink. This is because the liquid is denser and exerts a greater buoyant force on the object, causing it to sink until it reaches an equilibrium point where the buoyant force equals the gravitational force.
What makes igneous rocks?
Ultimately a combination of an increase in temperature or a loss of pressure cause the partial melting of mantle material (usually by decompression), or the partial melting of mantle material near a subducting slab due to the release of volatiles into the surrounding material, lowering it's melting temperature to a point where it becomes liquid. This lower density material will then be of higher buoyancy and migrate upwards toward Earth's surface where it will either form an igneous rock intrusion (where the molten magma cools and solidifies under the surface), or an extrusive igneous rock where the lava erupts onto Earth's surface and solidifies.
What is a hot spot in relation to volcanoes?
This is a point in the Earth's crust where hot upwellijng mantle material causes significant magma formation and melting to occur within the crust and upper mantle. This in turn causes hotspot volcanism at the surface.
