Answer:
It's B
Explanation:
A is going to evaporate more quickly causing it to push through the tube to beaker B.
The salt bridge prevents the direct mixing of one half-cell solution with the other and allows ions to migrate from one half-cell to another.
If the earth’s interior cools down then the convection currents will not be produced in the mantle and geologically leads to dead earth.
<u>Explanation:
</u>
Convection currents is the process by which the heated fluids will be made to float on the surface while the cooler fluids will get precipitated in the mantle. The high amount of heat in the earth's crust leads to transfer of them as magma on the surface of the mantle and then it will lose its energy and precipitate as tectonic plates.
So, convection currents leads to the movement and production of new tectonic plates. If the earth's interior gets cooled down, then the creation of convection currents will cease leading to a geologically dead earth.
Answer:
Scientific inquiry
Explanation:
A scientific inquiry is a systematic way of finding out about certain phenomena in our environment through the use of careful observations and experimentation. It follows a series of steps and procedures which helps a scientist to critically think and observe certain events in his environment. Through the observations, scientific conclusions are then drawn.
