Define the following Atmosphere Geosphere Hydrosphere Geocentric Heliocentric Hypothesis theory

Howdy, hope this helps!

Atmosphere - The layer of gases surrounding the earth

Geosphere - Any of the spherical regions of matter that make up the earth and it's atmosphere, as the lithosphere and hydrosphere.

Geocentric - Measured from or considered in relation to the center of the earth.

Heliocentric - Measured from or considered in relation to the center of the sun.

(Not quite sure what they require on the definition of Hypothesis theory, I'll try my best here)

Hypothesis theory - We know that a hypothesis is a tentative explanation or prediction, and we also know that a Theory is a substantiated explanation for an occurrence.
