(2 points) wrting part clearing large tracks of land of all trees removing some of the overpopulated animals from a forest controlled burning of the underbrush selective thinning of some trees 16. the two types of weathering are (2 points) water and wind mechanical and chemical mechanical and wind biological and wind 17. can any type of rock become igneous rock? (2 points) no, only volcanoes produce igneous rocks no, one type of rock cannot change into another type of rock yes, rocks at the surface can change from any type to igneous yes, if they are pressed down into the earth's core and melt and cool to become igneous rocks 1 8. list and describe two ways that scientists can date fossils found in the earth.

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
