The lowered surface in the water table around a well is called a cone of depression. It is caused by the pumping of water from the well, which creates a temporary lowering of the water table in that specific area. The cone of depression will become larger if there is excessive pumping from the well or if the water table is already low, and will become smaller if pumping is reduced or if the water table is replenished through natural recharge.

Which has the greater surface area one large cell or 27 smaller cells?

What is the surface pressures of mars?

Mars' surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure. The planet has a smaller mass and lower surface gravity than Earth, so it can only hold a thin atmosphere.


Why do you need to tie a piece of string around the solid while lowering it into a measuring cylinder?

I presume that you are trying to find the volume of an irregular solid. It is usual to tie a piece of thin cotton around the solid prior to lowering it into the measuring cylinder. This is so that you can control the decent of the object, i.e. it is not dropped into the cylinder causing the water to splash out, thus not giving an accuarate value for volume of the solid.

What would be the temperature if a plane flew up to 9 km?

Temperature will be lowered to -60 C. The temperature as we feel on the surface is higher than at altitude because air get the heat from the ground in form of conduction and convection. Earth surface is warm since it absorb solar radiation. Radiation mostly pass through air without affect so it didn't warm the air. It is earth surface that warm the air around the surface. Moving up high, we no longer have heat support from the surface and it is awful colder up there.
