(These Answers Should Be Used as a Basis For Yours)
Exercise 1.1 Submergence Rate Along the Maine Coast
The rate of submergence is the total change in elevation of the pier 2 meters divided by the total amount of time involved 300 years and is therefore .67 cm/yr
Exercise 1.4 Sources of Heat for Earth Processes
A. The sand should be hot since the sun has been heating up the sand throughout the day.
i. When you dig your feet into the sand you should feel cooler sand since the sun's penetration into the earth is limited.
ii. This suggests that the Sun can only penetrate into the Earth up until a certain depth.
iii.Based on this conclusion, one can assume that the Sun is not responsible for the Earth's internal heat since, we have heat hundreds of kilometers within the Earth and this can not be explained with the Sun's ray.
B. The geothermal gradient supports this conclusion because the deeper you get into the Earth the hotter it will get.
Exercise 1.6 The Challenge of Perspective and Visualizing Scale
A.
i. This flea is .0397 inches long
ii. The dog is 1000 times larger than the flea.
iii.The bar scale representing the flea is 1.35 cm long or .53inches
iv.The Bar would have to be 1,350cm long
B.
i. The earth is 640,000 larger than the geologist
ii.the drawing of the earth would have to be 281.6km long or 174.99 miles long.
Exercise 1.7 Moving Along
A. 8766 hours
i. 942,000,000km or 585,358,800miles
ii. its takes 8766 hours
iii. 107,460.64km/h or 66,776.04mph
iv. 1.074 x 10^5 or 6.676 x 10^4
B. 1674.67 km/hr or 1040.64mph
C. The person standing in between the equator and the pole will be moving at a slower rate since the circumference of the earth is smaller compared to that on the equator meaning the earth has less distance to travel in a 24 hr time span.
D.
i. it would take 20000 sodium atoms 2 x 10^4
ii. the period is 4 orders of magnitude bigger than the atom.
Exercise 1.8 Scaling Down Features to Visualize Them
A. The U.K would have to be scaled down by six orders to make it fit on paper of 20cm long.
Exercise 1.9 Picturing Geologic Time
A.4.75 x 10^3 inches or 7.49 x 10^-2 miles or 1.21 x 10^-1 km
B. 5.28 x 10^4 years would represented by one second
3.173 x 10^6 years would be represented per minute.
1.9 x 10^8 years per hour
C.It would take 1.0x10^8 days to save a million
i. you would save $10,000 in a million yrs
you would save $10 million in a billion years
Exercise 1.10 Rates of Mountain and Ocean Formation
A.
i. 1 meter high in 1000 yrs, 10,000 meters high in 10,000,000 years and 50,000 meters high in 50 million yrs.
ii. 1.96 x 10^-7 km/yr or 1.96 x10^-4m/yr or 1.96 x 10^-1mm/yr
iii.1.47m/yr or 1466.67mm/yr
iv. it would take 44,000,000 to erode
Exercise 1.11 Thinking about Pressure in the Earth
B.the lithostatic pressure at 8km would be 2.75kb.
