As you travel deeper in the ocean...

• Temperature increases
• Light increases
• Pressure decreases
• Temperature decreases

What is the most abundant salt in seawater?

• Magnesium Chloride
• Calcium Chloride
• Potassium Chloride
• Sodium Chloride

Why is the Dead Sea so salty?

• Water evaporates quickly in the hot, arid climate
• Fresh water is being added often
• Lots of fish have died in there
• People visit and pour salt into it
