Viscosity is the ability of a substance (in this case, lava) to resist flow. First of all, the temperature of the lava affects the viscosity. Lava with a higher temperature has lower viscosity than cooler lava (higher viscosity) since cooler lava is starting to solidify thereby increases its resistance to flow. The composition of the lava is also a determinant of viscosity such as the silicon content of the lava. The higher the silicon content of the lava, the higher the internal friction of the lava, thereby higher resistance to flow.
Answer:
Heat pollution is harmful to marine habitats because it changes the tempature of the water.
Explanation:
Can you take a better picture so that all of the words can be seen,maybe horizontally?
No, The magnetic north shifts overtime due to the rotation of liquid iron in the earth! So your answer would be No they are not always the same distance apart! Hope this helps :)
