What materials make up an aquifer layer?

As a stream slows down, which sediments are deposited first—large ones or small ones?

Water slows down when it reaches (permeable/impermeable) material.

Water flows in a horizontal pipe that is narrow but then widens and the speed of the water becomes less. The pressure in the water moving in the pipe is (a) greater in the wide part. (b) greater in the narrow part. (c) the same in both parts. (d) greater where the speed is higher. (e) greater where the speed is lower.

Water slows down when it reaches (permeable/impermeable) material.

Identify a wave that speeds up when it passes from air to water as well as one that slows down.

If the average temperature of the North Atlantic is $12.0^{\circ} \mathrm{C}$ and the Gulf Stream temperature averages $17.0^{\circ} \mathrm{C}$, estimate the net amount of heat the Gulf Stream radiates to the surrounding ocean. Use the details of Solved Problem $18.3$ (the length is about $8.00 \cdot 10^3 \mathrm{~km}$ ) and assume that $e=0.930$. Don't forget to include the heat absorbed by the Gulf Stream.

Why were some southern leaders worried about the South's reliance on cotton?

What is the importance of the Gulf Stream?

Why was Benjamin Franklin interested in the Gulf Stream?

What is a mesocyclone and how does it form?

What is a mesocyclone?

Explain why a cold, dry air mass produces a higher surface pressure than a warm, humid air mass.

The Saftir-Simpson scale, used ty the National Weather Service since the I970s to classify hurricane strength, ranks storm strength from Level 1 to 5 , and is used to give an extimate of the possible property damage and flooding expected when the hurricane makes landfall. A Categocy 5 storm maintains winds in excess of 155 mph and is capable of causing widespread damages such as destroying or causing extensive structural damage to homes. It can also trigger a stocm suige moee than $18 \mathrm{ft}$ above normal.

Two of the most fundamental steps people can take are ssembling a disaster sapplies kit and making an emergency plan. They are simple meisures, but can make all the difference when disasters strike. 17. For what parpose is the Saffir-Simpoon scale used? A. estimating property damage and flooding efhen a hurricane makes landfall B. estimating the height of a stoem surge above normal C. determining who should be told to evacuate before a hurricane hits D. measuring the strength of an approashing hurricane 18. What can be inferred from this passage? A. Only Category 5 harricanes will cause major damage. B. Only people living along the shoreline are in danget during burricanes. C. Category 5 hurricanes have the potential to cause major damage, D. People should have a disaster supply kit or an evacuation plan in place before a burricane hits.
