Question

What is tephra falls and ballistic projectiles?

Answer 1

Answer:

Tephra falls and Ballistic Projectiles formed on Land

Ballistic projectiles are rocks that an erupting volcano may hurl into the air. These blocks and bombs travel like cannonballs and usually land within 2km of the vent (but can travel as far as 5km, or even further, if the eruption is very explosive.)

The term tephra defines all pieces of all fragments of rock ejected into the air by an erupting volcano. Most tephra falls back onto the slopes of the volcano, enlarging it. ... Shaded areas indicate where tephra layers remain from associated very large eruptions.
