What is the difference between andesitic and basaltic lava?

By Ritesh|Updated : September 8th, 2022

The difference between andesitic and basaltic lava is that Basaltic lava has a low viscosity and is more liquid, whereas andesitic lava is an example of high viscosity lava. The andesitic lava's high silica content contributes to its high viscosity, whereas the basaltic lava's low silica content accounts for its lower viscosity. The basaltic lava forms from the hot mantle material at constructive plate borders and hotspots, while the andesitic lava forms at destructive plate boundaries from the melting crust.

Key Difference Between Andesitic and Basaltic Lava

Andesitic lava:

  • It has little potassium and sodium and significant iron, magnesium, and calcium levels.
  • It has a temperature range of roughly 800 degrees Celsius to 1000 degrees Celsius.
  • Stratovolcanoes release thick lava flows made of andesite magma that are sometimes several kilometers long.

Basaltic lava:

  • It has a low potassium and sodium content but a high iron, magnesium, and calcium concentration.
  • Its temperature is between 1000 and 1200 degrees Celsius.
  • When they erupt, basaltic lavas are quite fluid and relatively thin.
  • Basaltic lava comes from shield volcanoes.
  • Of all the volcanoes on Earth, they are the biggest.
  • The most well-known examples are the volcanoes in Hawaii.

Summary:

What is the difference between andesitic and basaltic lava?

The difference between andesitic and basaltic lava lies in their temperature. Andesitic lava has a temperature range of 800 - 1000, while Basaltic lava's temperature range is between 1000-1200 degrees Celsius.
