Chapter 5, Problem 5QQ

Choose the best answer to each of the following. Explain your reasoning.

What do we conclude if a planet has few impact craters of any size? (a) The planet was never bombarded by asteroids or comets. (b) Its atmosphere stopped impactors of all sizes. (c) Other geological processes have erased many craters.

Radiocarbon dating is the most common and important absolute dating technique in archaeology. The method has proven invaluable for providing calendar dates for a range of different materials and many different time periods. Radiocarbon dating, however, is not without its limitations and uncertainties, so it is important for archaeologists to be aware of a range of issues when using the technique. For the second part of this assignment, please answer the questions below.  6. List two kinds of archaeological materials can be dated using the radiocarbon method and two that cannot be dated with radiocarbon.  7. In one or two sentences, explain why radiocarbon ages need to be calibrated into calendrical ages?  8. A radiocarbon date on wood charcoal was obtained from Layer N in the stratigraphic profile above. The date has a radiocarbon age of 5500 BP ± 50 yrs and it calibrates to 4450-4260 cal. BC. Burial W in Layer E was also dated and has a radiocarbon age of 5000 BP ± 30, which…
Problem 2. Planetary Body Composition:  Density (Links to an external site.) of the Earth  (Palen, et. al., 1st Edition,  Chapter 6, problem 70) Earth’s mean (Links to an external site.) radius is 6,378 km and its mass is 5.97 x 1024 kg. CALCULATE Earth’s average (Links to an external site.) density. SHOW YOUR WORK. DO NOT LOOK UP THIS VALUE! The average density of Earth’s crust is 2,600 kg/m3. What does this tell you about Earth’s interior?
We need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion:      4879km×30cm1392000km=0.105cm    or    0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…
