During which event does the moon appear closer? a. Apogee b. Penumbra c. Perigee d. Umbra

Hello!

Your answer must be C. PERIGEE!

Explanation:

What is a PERIGEE?

A perigee is just another word for "near Earth"...when our Moon is at the closest point ever during orbit from the centre of the Earth...

When this happens, FULL MOONS may be seen as well as significant tidal changes!

HOPE THIS HELPS!!

the answer to your question is sperm

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.
