What is the apparent weight of the floating block when a block of wood is floating in a lake?
Zero.
How much less does a body weigh in water vs land?
A body weighs the same in water as on land. because water is more dense than air, the body APPEARS to be lighter, but it is notAnswerTo determine the weight of any obect in water that is not floating subtract the weight of an equal volume of water (the amount of water displaced by the object) from the weight of the object when outside of the water.
Why are you more buoyant in a swimming pool or a lake than on land?
Water is denser than air.
Is the buoyant force caused by the increase in density in depth fluid?
Buoyancy is proportional to fluid density but the question seems to imply density increasing with depth. Gases such as the atmosphere behave in that way. Liquids do not because they are to all intents and purposes incompressible. A cubic metre of water in Lake Baikal would still have a mass of 1Tonne whether at the surface or down at the bottom.
Why the lake is greenish blue?
The color of a lake may just be the color of the sky, reflected in the lake, but if the water itself is actually greenish blue, that is caused by algae.

An object that weighs 340 N floats on a lake what is the weight of the displaced water?
buoyant force acts on the object from its bottom and push it outside..the magnitude of the buoyant force acting on the object will b equal to the weight of displaced water..

I am in a boat on a fresh water lake. In my hand is a rock. I throw the rock into the lake. How is the lake's water level affected?
It goes down.. the reason is buoyancy by Archimedes' principle, buoyant force = weight of displaced liquid = m*g = rho*V*g #if rho and g of the fluid are constant (which is the case when u r in a lake) it is the variation in buoyant force that affects the volume of displaced fluid buoyant force arises as a result of P diff bet the top and bottom surfaces of an object put in a liquid.. if its floating, one side its ATM P and other side P on the lowest surface of the object inside the liquid... if its immersed, due to Pascal Law, 2 diff P are goin to act Situation A: rock in ur hand ur boat floats... so the buoyant force is capable of counteracting the weight of the entire boat (no matter whatever weight is der... u, rocks or anything.. u jus have 2 keep the structural integrity of the boat so that it floats - that's why we avoid overloading) say weight of rocks is W1 and the rest weight W2... now B.F. = W1+W2 Situation B: rock thrown in water consider W1 and W2 separately... for W2, as it is still floating, B.F.2 = W2 for W1, as it has sunk, tis clearly implies that ur B.F.1 was not able to cancel W1.. that's why the rock has sunk.. the difference between these two is trimmed out and the rock is maintained in equi. by the normal reaction the rock has at the ground... hence B.F.1 = W1 - R So, B.F. = B.F.1 +B.F.2 = W1+W2-R By point #, we can see that second situation displaces less vol than the first So, water level goes down
