The outer and inner core of the earth make up approximately one third of earth’s mass.

true

false

False

Explanation:

Earth is divided into three parts, namely-

a) Crust

b) Mantle

c) Core

The core, including the inner and the outer core, starts from the depth of about 2900 km up to 6400km. It is a depth greater than the depth from the surface of the earth to the lower limit of the mantle. It is comprised of the denser materials here, where the outer core is liquid and the inner core is solid. The density is maximum here. Since density and mass are directly proportional, so it can be considered that the mass also is significantly high in this region. It covers more than about 50% of the earth's total mass.

Thus it does not form one-third of the earth's mass.

hence, the above-given statement is false.

no but i do not usually comment or use my voice that much when it comes to social media

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
