These are substances that destroy other materials by chemical reaction. When in contact with human tissues, these substances may cause burns and destroy tissue. Common examples of these substances are oven and toilet cleaners." This describes what type of hazardous substance?a. corrosiveb. infectiousc. explosived. flammable

option A) corrosive

Explanation:

A substance is said to be corrosive when it has the ability to wear away or destroy gradually other non-living materials OR harm living tissues by dehydrating them, thus resulting in burns and deep scars

weathering is the answer.

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.
