Question

1. Which volcano type from the choices below can experience a plinian eruption?

a. Stratovolcano/Composite       b. cone       c. inder cone Shield volcano

2. Water __________ when it freezes.

a. expands         b. contracts       c. stays the same

3. A very slow slide of unconsolidated material that travels as a unit is called:

a. slump         b. soil creep         c. debris flow         d. mud flow

4. At the bend in a stream, the main erosion is __________.

           a. on the outside of the bend

           b. on the inside o the bend

           c. both on the inside and the outside of the bend

5. All asteroids orbit Earth. (T/F)

Explanation / Answer

answer 1 - composite / stratovolcano

plinian kind of eruption is the most voilent kind of euption. which is common in volcanoes which erupts highly viscous and gaseous magmas like stratovolcanoes.

answer 2 - expands

water usually expands about 9% when it freezes.

answer 3 - slump

slump is a kind of mass wasting, in which loose unconsolidated mateial slides very slowly in a curved fashion.

answer 4 - on the outer side of the bend

in a meandering stream, erosion occurs at the outer bend because the velocity is maximum here while deposition occurs at inner bend.

answer 5 -false

most of the asteroids orbits the sun in an asteroid belt between the mars and jupiter.
