After a direct blow to the eyeball with a soccer ball, your athlete complains of double vision and numbness in her cheek. you also notice that she has noticeable swelling and a downward displacement of the injured eye. what injury might you suspect?

In the given case, one may suspect for an orbital fracture.  

An orbital fracture refers to a traumatic injury to the eye socket bone. These injuries are generally the outcome of blunt force trauma to the eye. There are three prime kinds of orbital fractures, which can take place:  

1. Orbital rim fractures take place in the eye socket's bony outer edges.  

2. The blowout fractures take place when the rim remains intact, however, a crack produces in the wafer-thin bone, which forms the eye socket floor.  

3. Direct orbital fractures refer to the rim fractures, which have elongated into the floor.  

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.

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.
