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.
The changing ocean currents lead to climate cooling by bringing cooler breezes to places with higher climates. The cool breezes push the warm air out and leads to the drop of temperature
Answer:
Some geologic processes happen quickly, while others happen over millions of years.
Explanation:
uniformitarianism and catastrophism are geological terminologies which are used to describe events.
Catastrophism is a term used in geology to explain the theory that the Earth is shaped by sudden occurrences which takes place from time to time,these events don't last long.
Uniformitarianism is a terminology used in geology to explain that the Earth is shaped by gradually occuring events or activities which takes place over time, Uniformitarianism can also be described as GRADUALISM.
