Introduction to Geology and Measuring Earth
1.
Geologic Time Scale
a.
When you look at the Geologic Time Scale, where are the more recent events, top or bottom?
b.
What is the age of the Earth?
c.
The dinosaurs lived during which era?
d.
When did Pre-Cambrian Time begin and when did it end?
e.
When did the Carboniferous Period begin and when did it end?
f.
How long ago (approximate date) did the first humans appear?
g.
What do the names of the following ERAs mean?
Paleozoic
Mesozoic
Cenozoic
h.
Which Era is known as the age of the reptiles?
i.
Did life exist during the Pre-Cambrian?
2.
Spheres of Earth
Define the following:.
a.
Geosphere
b.
Hydrosphere
c.
Atmosdphere
d.
Biosphere
3.
Mass and Density
a.
What is the density formula?
b.
What is the density of a mineral with a mass of 48.6 grams (g) and a volume of 18 cubic centimeters
(cm3)? if your answer does not have the correct units, it is wrong!
c.
Is this mineral more dense or less dense than water?
d.
Would this mineral float or sink in water?
e.
*Must do parts e and f in the classroom.
Use the mineral samples provided: #2 and #41. Hold one in each hand.
Which one do you think has a higher density?
Explain your answer.
f.
Find the density of each by using the water displacement method.
1. Weigh the dry minerals and record the mass in grams in the chart below.
Then Fill the density cup with water. Hold a small glass beaker or graduated cylinder
spout and drop the mineral in.
Measure the overflow of water in ml. (1 ml = 1 cm3 ) Record the amount on the chart.
