Question
Chapter 18, Problem 1QR
To determine
The term fossil and whether a footprint can be considered as a fossil.
Expert Solution & Answer
Answer to Problem 1QR
The term fossil is defined as the evidence of former life. So, footprints can be considered as fossils.
Explanation of Solution
The naturally preserved remains or traces of plants and animals that lived in the past are known as fossils. The two requirements for an organism to become fossilized are the presence of hard body parts and rapid burial.
Footprints are trace fossils that provide the physical evidence of the life activities of extinct organisms. A footprint is a trail left behind by an ancient organism in mud or clay. For example, the footprints left by dinosaurs are considered fossils.

- I need help with part A, B and Carrow_forwardDiscussion Question: Atmospheric Water & Weather A+ This chapter beautifully focuses on water from the small molecular scale to large-scale weather patterns. The surplus of heat at the equator and the deficit at the Poles drives our atmospheric instability. Instability is a good thing! Without the unstable conditions, there would not be any atmospheric motion. The overheating of the equator pumps atmospheric uplift. As the air rises into lower pressures, it expands and cools... adiabatic cooling! The air migrates north and south and becomes denser than the surrounding air and sinks. The sinking air enters higher pressures and creates the subtropical high pressures and adiabatic heating...whaaaa-la! We have Hadley Cells! Not to mention, the Rainforests and World's largest deserts too! We now can imagine the Hadley cells in three-dimensions. They more or less "sandwich" the equator during the spring and fall equinoxes. However, what happens in the summer and winter? mP Maritime polar…arrow_forwardUsing the map.
