Analogy: vesicular is to trapped bubbles as coarse-grained is to large mineral particles.

true or false

TRUE

Explanation:

The vesicles refers to the small and large holes that are commonly found to be present in the extrusive igneous rocks. These are mostly present in the volcanic rocks. These vesicles used to trap gases such as Water vapor (H₂O), Nitrogen gas (N₂), Carbon dioxide (CO₂), Methane (CH₄), Sulfur dioxide (SO₂), and Hydrogen sulfide (H₂S). These gases are released into the atmosphere where they escape the bubbles.

For example, Pumice, Basalt, and Obsidian.

These bubbles cannot hold the coarse-grained minerals because it has the capacity to hold only the gaseous elements.

Hence, the above statement is TRUE.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
