Question

which statements describe geologic gaps? check all that apply. geologic gaps happen when volcanoes erupt. when no sediment is deposited for a long time, angularities can result. an unconformity happens when rocks do not follow normal geologic rules. a geologic gap happens when rock is eroded before sediment is deposited. an unconformity occurs when a rock layers relative age can be determined.

Explanation:

Geologic gaps are related to sediment - deposition absence, rock - layer irregularities (unconformities), and erosion before deposition. Volcanic eruptions don't directly define geologic gaps. Determining a rock layer's relative age is not what defines an unconformity in terms of geologic gaps.

Answer:

• When no sediment is deposited for a long time, angularities can result.
• An unconformity happens when rocks do not follow normal geologic rules.
• A geologic gap happens when rock is eroded before sediment is deposited.
