1. where are tidal bores most common?

deep ocean basins

beside glaciers

shallow estuaries

lakes

fjords

Explanation:

Question 19

To solve this, we analyze each option:

• "tide table" is a table predicting tides, not a difference.
• "tidal max" is not a standard term for this difference.
• "average tide" is a mean, not a difference.
• "tidal range" is defined as the difference between the highest high tide and lowest low tide.
• "tide level" refers to a specific water level, not a difference.

Tidal bores are a tidal phenomenon where a wave of water moves upstream in a river or estuary. They require a combination of a large tidal range and a shallow, narrowing estuary.

• Deep ocean basins don't have the conditions (narrowing, shallow) for tidal bores.
• Glaciers are unrelated to tidal bore formation.
• Shallow estuaries provide the necessary conditions (shallow water, narrowing channel) for tidal bores to form as the tide moves in.
• Lakes are generally not dynamic enough with tidal forces like estuaries.
• Fjords are deep and narrow, not shallow, so not ideal for tidal bores.

Answer:

D. tidal range
