How does the density of air in a deep mine compare with the air density at the earth's surface?
Air is compressible (i.e. when you squish it it gets denser). This means that the air at the top of the atmosphere is less dense than the air lower down in the atmosphere because the weight of the air above squishes the air below it. If you go up in a lift in a tall building, your ears 'pop' because the air at the top is less dense than the air was at the bottom.
As you go down a mine there is more air above you than at the top of the mine shaft so the air gets progressively denser the deeper you go. At the bottom of the mine the air is, therefore, more dense than at the earth's surface.

What will happen if the density of surface water in the lake does not change?
If the density of surface water in a lake does not change, then the water at the surface will maintain its relative position compared to the denser water beneath it. This will result in stable stratification, with the surface water layer remaining on top and the denser water layer staying below.
What is the difference between a surface current and a deep current?
Well, honey, a surface current is like the diva strutting her stuff on the runway - it's the flashy, visible movement of water caused by things like wind and tides. On the other hand, a deep current is more like the mysterious loner lurking in the shadows - it's the slow, hidden flow of water deep below the surface, driven by differences in temperature and salinity. So, in a nutshell, surface currents are the show-offs, while deep currents are the silent movers and shakers of the ocean.
What causes deep currents to flow?
Deep currents are primarily driven by differences in water density caused by variations in temperature and salinity. Cold, dense water sinks and flows along the ocean floor, while warmer, less dense water rises and flows near the surface. These density differences, combined with the Earth's rotation and topography, generate deep ocean currents.
If you know the width length and mass of a boat how can you calculate how deep it will sink in water?
Well, darling, to calculate how deep a boat will sink in water, you need to consider its volume and density. The volume can be calculated by multiplying the length, width, and depth of the boat. Then, you can divide the mass of the boat by its volume to find the density. Finally, you can use the density of water to determine how deep the boat will sink. Voila!
What is a sentence for the word density?
"The density of a substance is defined as the ratio of its mass to its volume."Deep within the Sun, gravity increases the density, and allows fusion to occur.""In pancakes, the density is very important; the fluffier, the better."
What is the primary difference between surface currents and deep currents?
Compare and contrast surface currents and deep currents. They are both are moving water that flows through oceans. Surface currents are towards the top of the ocean, can be warm or cold, and are controlled by winds. Deep currents are low, deep in the ocean, cold, and are controlled by density.
What is the earths surface from the edge of a continent to the deep part of the ocean?
continental shelf
What type of rock can form deep below earths surface or above?
igneous
If Heat and pressure deep beneath the earths surface can change any rock into?
... the fluid state we call 'lava'.
Heat and pressure deep beneath Earths surface can change any rock into rock into?
... the fluid state we call 'lava'.
Which theory explains the processes that shape the Earths surface into mountains deep-sea trenches and oceanic ridges?
plate tectonics
What is the name of the rock that churns deep beneath the earths surface?
The rock that churns deep beneath the Earth's surface is called "magma." It is a molten rock material that is located beneath the Earth's crust and can eventually rise to the surface as lava through volcanic eruptions.
How do surface currents differ from density currents?
The same thing! Deep Currents Occur when the density of the water increases. Density is based on two main things it is the civility is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. The denser the water the more it was to go down. The less dense the water wants to rise. The temperature is what causes the dense. Deep current:A streamline movement of ocean water far below the surface.
What is the complete predicate in volcanoes are places on the earths surface where molten rock gases and ash from deep inside the earth are ejected?
"are places on the earth's surface where molten rock, gases, and ash from deep inside the earth are ejected."
Compare the causes and effects of deep currents and surface currents?
deep currents form when dense water neat the poles sinks and flows slowly along the ocea floor
How did diamonds arrive on the earths surface?
Diamonds are formed deep within the earth's mantle, under enormous pressure and extreme, high heat. Then, volcanic pipes erupt the diamonds to the earth's surface.
What can change any rock into a metamophic rock?
Heat and pressure deep within the earths surface can change any rock into a metamorphic rock. your welcome.
