A1. Ultimately, surface water can sink as low as it wants until the following happens: The deeper you go, the colder it gets (generally). At 0 degrees water freezes, and at 4 degrees, water is in its most dense state. As water sinks, it will get colder and colder until it reaches 4 degrees. At 4 degrees the water should be at the bottom. If the water goes below four degrees, the water starts to rise up again and be replaced by water that is closer to 4 degrees. It really depends on the temperature.
A2. But the base of glacial lakes is commonly scoured out by their original glaciers to below sea level. [And the land may have sunk as well.] Without research on the subject, I'd not be surprised to find out that some of the world's great artesian basins extended below sea level. [Sahara, Great Australian artesian basin, + .. Canada? ..]
Both answers probably refer to fresh water. Ignoring the oceanic trenches.

What makes things sink or float in the water?
Short AnswerWhether something sinks or floats in water depends on how much it weighs. Water weighs one gram for one cubic centimeter, or one kilogram for a liter. Anything that weighs less than one gram for one cubic centimeter will float, but anything heavier than that will sink. Long AnswerThe buoyancy of an object (i.e. whether it sinks, floats, or stays where it is) depends on the pressure of water at that depth and the downward pressure exerted by an object on the water. Water pressure increases with increasing depth based on the relationship ρ*g*h, where ρ is the density of water (1000kg/m3), g is the acceleration due to gravity (approximately 9.8 m/s2), and h is the height (in meters). The pressure exerted by the object depends on the relationship (m*g)/A where m is the mass of the object, g is the acceleration due to gravity, and A is the surface area perpendicular to gravity (for instance, a for a cylindrical barrel floating upright, the surface area of the bottom of the barrel would be A). The resulting comparison will tell you how deep the object will sink. You are essentially looking for the point at which ρ*h = m/ABy looking at these relationships, you might notice that every object with mass sinks somewhat. No object truly floats on the water; it simply does not sink to a depth where the object is entirely below the water line. Some creatures are able to walk on water; however, this is by utilizing the water's surface tension rather than actually "floating".The Density of Water is one gram/ cubic centimeters. NO MATTER WHAT!
How necessary is soap in removing salt from your hands?
Soap is not necessary for removing salt from your hands. Salt is very easy to clean off your hands with just water.
What is the relationship between a water table and a well?
If you want to get water out of your well, you need to drill down below the water table in able to pump it out. That should be kind of obvious. The only other neat point that you make is that if the topography dips below the natural water table, then the water in the aquifer (the rock holding the water) will be exposed at the surface. This is called an artesian well, and this is what makes the famous desert oasis happen.
Why is there an upward force on objects in a fluid?
Because an object has to displace an equivalent volume to be able to sink. Say you dropped a brick into a bucket of water, brick and water cannot occupy the same space at the same time so for the brick to sink it has to "displace" or move a volume of water equal to the size of the brick. That's why when you get in the bath the water level rises - you have displaced a volume of water equal to the size of your body.
Does the shape of a sponge affect how much water it will absorb?
Oh, dude, totally! The shape of a sponge can totally impact how much water it absorbs. Like, if you have a super flat sponge, it might not be able to soak up as much water as a thick, chunky one. So, yeah, the shape totally matters when it comes to sponge absorption.
How does the water level effect the pump?
The further any Pump has to lift or push water to get it to the surface the less pressure it will be able to make as an end result. More horsepower and Impellers are required as the depth to water increases.
How do the word use surface tension?
A water skipper is able to walk on water based on surface tension.
Could you ride a ATV in water?
it depends on the depth of the water and the size of you ATV but you should be able to go though some water
Why does an oasis disappear?
If the water table drops the water may no longer be able to surface as a spring so water will disappear from the surface of the desert and the oasis will disappear.
Does a paperclip float in water?
Yes a paper clip is able to float in water. Take a bowl, fill it up to the top with water, take a paper towel and put it into the bowl, let it sit there for 3 seconds...then put the paper clip on it, and slowly remove the towel. This is able to work by Surface tension.Depending on the size, some paperclips can due to the high surface tension of water.
Why does the pin rest on the surface of the water when it denser than the water?
The pin rests on the surface of the water due to surface tension. Surface tension creates a "skin" on the water's surface that can support objects with low surface area, like a pin. The pin is able to float because the force from surface tension is greater than the force pulling it down due to gravity.
Why dams are provided with wide base area?
The weight and pressure is greater as the depth of water increases. The wide base is better able to withstand such forces. As the weight and pressure is less near the surface, the top of the dam wall doesn't need to be so wide.
What mean by watch is 30 m water resistant?
Means that the clock is supposed to be able to be submerged to a depth of 30 meters w/o taking in water.
An insect is able to walk on water because of the property known as?
surface tension. This property is caused by the cohesive forces between water molecules, which allow the insect to stay on the water's surface without sinking.
Could a thumbtack float or sink?
A thumbtack is typically denser than water so it would sink if placed in water. However, if the surface tension of the water is strong enough, a thumbtack might be able to "float" on the surface, supported by the surface tension.
The ability of some organisms to be able to walk on water is due to which property of water NAME the property?
The property of water allowing some insects and other animals to walk on its surface is called "surface tension".
Why does the water kept in a plate evaporate faster as compared to that kept in a test tube?
The water surface able to be evaporated is greater.
