the type of plant
the growth of the plant
the amount of fertilizer

A geologist was exploring a deep cave in the desert, and discovered a fossilized school of fish. Which option below most likely explains why the geologist would find fish fossils in a desert cave?
Local wildlife went into the cave and had brought the fish to eat and then left, the fish scraps left behind in the cave became fossilized.
During the recent rainy season fish were able to swim in the flood waters to the cave, once trapped, they died and were fossilized in the rock.
Millions of years ago the desert was a lake that had fish, over time the Earth changed, the lake became a desert, and the fish in the lake were fossilized.
A few hundred years ago the lake that was there was used to irrigate the local farm lands and the lake was drained leaving the fish in the lake to be fossilized in the rock.
In 1997 a team of scientists discovered three fossilized skulls and other artifacts at a dig site in Ethiopia, Africa. Since it is difficult to determine the age of once-living organisms, the scientists used radioactive dating on the igneous rocks that surrounded the remains to determine their age. Why would scientists use radioactive dating in order to determine the age of the fossil they discovered?
Law of superposition is a more expensive method to apply than radioactive dating for estimating the age of a rock
Law of superposition is specific and gives the date that the rock was formed while radioactive dating gives an estimate of the age.
Radioactive dating determines whether the igneous rocks are older or younger, while the using the law of superposition depends on tectonic events.
Radioactive dating gives an estimated date that the rock was formed, while the law of superposition will only reveal which rock is younger or older.
Heat generated by the core is passed to the mantle by conduction. Which option below best describes how the flow of heat through the mantle affects the movement of the Earth's tectonic plates?
Heated material in the mantle expands and rises towards the crust where it then cools, forming a convection current, which causes plate motion.
Heat is transferred from the mantle to the crust by radiation, which then causes the plates to move on the surface.
Heated material in the mantle rises to the surface forming a heated cell, which causes the crust to harden and move the plates.
Heat conducted from the Earth's mantle moves tectonic plates due to the gravitational pull from the Earth's core.
A group of scientists are studying two tectonic plates. When they analyzed the data, they noticed that the two plates have been pushing against each other over the past ten years. What option below describes what will most likely occur between the two plates?
The two plates will quickly transform causing the formation of a canyon.
The plates will slowly converge causing a mountain to form.
The two plates will slowly subduct causing an earthquake.
The two plates will quickly diverge forming an ocean basin.
