You have been tasked to estimate the number of rattlesnakes in the desert by Lone Mountain. You capture 42 rattlesnakes and tag them on the first day. You return to the
site one week later and capture 59 rattlesnakes. Of the 59 you caught, 21 are marked
from the first sample. How many rattlesnakes are in the population?

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
