The environment is in trouble, each level under attack,
answer each question,
and together they'll put you on the right track.
Be sure to use your clues,
and look for the letter,
keep only the one that begins each answer,
and together they'll work better.

1. This level of environmental organization is the part of Earth where life exists.
2. A group of individuals of the same species that live together and interact in an area describes this level of environmental organization.
3. This level of environmental organization is described as all of the populations of species that live and interact in an area.
4. A community of organisms and the abiotic environment of the community describes this level of environmental organization.
5. A living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis.

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 rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
