Answer:
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Explanation:
Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. ... Seafloor spreading proves that the ocean itself is a site of tectonic activity.
Answer:
When sugar dissolves, the particles break apart. These particles mix with the small water particles. The small water particles fit in the spaces between the larger sugar particles.
Explanation:
The data provided is of specific heat
The relation between specific heat, heat absrobed and temperature change is
Q = mass of substance X change in temperature X specific heat
Now if we have provided same amount of heat to two substances of different specific heat, the substance with lower specific heat will heat up more as compared to the substance with higher specific heat.
[Specific heat is the amount of heat absorbed by a substance (say nickel) to raise it temperature by one degree if we have taken one gram of substance]
Higher the specific heat higher the heat required to raise the temperature upto same extent.
Thus as the specific heat of Nickel is less, it will heat up easily
Answer: Granite, because it needs to absorb more energy to increase its temperature
Answer:
B) 
Explanation:
The total ionic equation contains all the species in the reaction in the ionic form.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
Spectator ions are also written in total ionic equations.
The chemical equation is:
The total ionic equation is -
