With reference to acidic lava ,consider the following statements :
1. they are viscous and flow slowly
2. they form a flattened lava dome
Which of the statements given above is/are correct ?

1 only

2 only

Both 1 and 2

Neither 1 nor 2

Explanation:
Acidic lava are viscous and hence flow slowly. They even solidify before flowing for any significant distance. This results in formation of steep sided cone. Flattened lava dome are formed by basic lava which are very fluid and hence travel great distance before getting solidify.
