Will give 50 ! 10 science
1. the table compares the features of two plant species that exist near the shoreline in south florida.
tree species data
tree species shade provided
native low
exotic high
the nesting sites of sea turtles are more successful when the sites have more sunlight and warmer temperatures. using the information from the table, predict how the type of tree species at the nesting site would impact the sea turtle population.
if there are more exotic species then the sea turtle population will increase.
if there are fewer native species then the sea turtle population will increase.
if there are fewer exotic species then the sea turtle population will increase.
if there are more native species then the sea turtle population will decrease.
2. which of the following natural factors is likely to support the formation of an oceanic island?
erosion of undersea stalagmites and stalactites
erosion of the face of a cliff by waves
rising of magma from the seafloor
rising sea level in low-lying areas
3. at a location, rainwater runs off the face of a cliff that is 15 meters high. how is the face of the cliff likely to change over time?
weathering by water would cut its middle deeper than the top.
weathering by water would cut its top deeper than the middle.
the top would slope gently due to deposition of sediments.
colored mineral streaks would be formed due to erosion.
4. what is the energy change taking place when an arrow is released from a bow?
potential energy to kinetic energy
kinetic energy to potential energy
radiant energy to chemical energy
chemical energy to radiant energy
5. which statement is correct about gasoline when it is burned?
heat energy is created by the gasoline.
the total energy of the gasoline decreases.
chemical energy in the gasoline is destroyed.
chemical energy is transformed into heat energy.
6. which of the following could be a characteristic of the fossil that is most closely related to humans?
arms longer than the legs
walking on four feet
large brain size
tree-dwelling
7. how is earth's surface likely to change when a river flows over a steep landscape?
its channel becomes wider than deeper.
its channel forms curvy loops.
a narrow valley is formed.
a lake is formed.
9. what may happen if there were no convective currents in the mantle?
oceans will turn completely dry.
continents will start breaking apart.
the recycling of earth's crust will stop.
the diameter of earth will start increasing.
10. a scientist observes plant roots growing through the mountain side. this is evidence for which type of natural process?
physical weathering
chemical weathering
erosion
deposition
