Hello! We know that water boils at 100 °C. The surface of Venus is 461.85 °C. If you take this into effect, we know that water can't be on the surface of the planet! Venus is the hottest planet in the solar system, however, Mercury has the most extreme temperatures. So, when you cancel these out that should leave you with your answer!

I hope this helped!

it would be volcanic activity. since there is no water available on the surface and the high pressure and temperature it would be volcanic activity. and mercury has the most extreme temperature.

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.
