•the lowest point of a wave is

•the level of earths oceans

• sound waves to the sea floor at an angle.

• the periodic rise and fall of sea level.

• is caused by differences in the temperature and salinity of ocean water.

•the upward motivation of ocean water is

•the highest point of a wave is

•waves that collapse near shore are

not really sure but:

1.D.) A "Breaking wave" is described as a wave that is not confined to the space along the medium

2.) C) Traveling Wave

3.) D) Constructive interference is occurring

4.) A) In a longitudinal wave, particle displacement is parrallel to the direction of the wave motion

5.) C) Region of high pressure in a medium caused by a passing wave

6.) A) Does require a medium to transfer

7.) D) Wavelength is the speed at which a wave travels

hope this helps

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
