Question 9

What are lumps of minerals that are made of
oxides of manganese, iron, copper, or nickel that
is scattered in groups on the ocean floor?

Nodules
Question 10


A sea is partially covered by land
Question 14



The study of the ocean and it’s properties
Question 15

the salinity of ocean water? (There are two)
Density
 Light
 Energy
 Chemicals
 Temperature


Density and temperature
Question 16


water?

Desalination
Question 17

What is a layer of body of water in which water
temperature drops with increased depth faster
than it does in other layers

Thermocline
Question 18


water to the surface is called..

Upwelling

Question 20

If sonar is used to measure the depth in a
particular area of the ocean and the time it took
for the waves to hit the ocean floor and then the
surface of the ocean was 3.9 seconds and the
speed is 1400 ft/sec, what is the depth.

700 ft/sec x (3.9 sec) = 2730 ft
Question 21

What is the density of oxygen gas if 0.369 g
occupies a volume of 567 mL?

0.369 g / 567 mL = 6.51 g/mL
Don’t forget your units!!!


3cm x 4 cm. If the mass of the wood is 456 g,
what is the density of wood?

(5cm x 3cm x 4cm)= 60 cm3
456 / 60 cm^3 = 7.6 g / cm3
