What is a benefit of food packaging technology such as milk cartons?

Milk packaging is designed to be attractive to the customer, give information, ease transport and to protect the product to maximize shelf life.  Tetrapak cartons protect the product from light, air and microorganisms.

To increase the shelf life of milk.

Explanation:

The benefit of packing milk in cartons is that it increases the shelf life of milk. These cartons are made of plastic, food safe polyethylene.

It protects the milk from contamination. This type of packing also protects milk from sunlight, dust and harmful microorganism which can spoil the milk.

So, to protect the milk from being sour and spoil, cartons is used for the package of milk.

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.
