Take a piece of paper and write down at least twenty things that animals contribute to your life and the lives of those around you. Once you have the list, select five and describe them in detail. Include the following in your description: What is the item, and how does it relate to animals?
What role does that item play in your life and the lives of those around you?
How was that item produced?
Describe the animal (size, type, what they feed on, how they live, etc.).
Your description of each item should be about 30 words long, for a total of at least 150 words. You will need to use your skills of observation and will also need to do some research on your own. Please submit the list and the descriptions.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

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.
