Answer:

mass

Explanation:

The density of a substance is defined as the ratio of mass of the substance to the volume of the substance.

It is a scalar quantity.

Density = \frac{mass}{volume}

Its SI unit is kg/m^3.

By comparing the densities we get the idea about how dense the substance is.

For example, cotton and iron, the density of cotton is much less than iron so the cotton is less dense than iron.

The relative density is defined as the ratio of density of substance to the density of water at 4 degree C.

The density of water is maximum at 4 degree C.

Which statements describe features that maps and globes share? Check all that apply.
leonid [27]

Maps and Globes share the following features:

Both are scale Models.

Explanation:

A globe is a scale model of the Earth that presents the most accurate depiction of geographic information such as area, distance, and direction.

A map is a two dimensional representation or a drawing of the earth’s surface, or a part of it, on a flat surface, according to a scale. Thus it is also a scale model.

A globe differs from a map. It is a three dimensional sphere representing the whole Earth.

A map is usually used to represent a specific part of the Earth and is used for Navigation. It has details and symbols. However, a globe can not be used for such details.

A globe can be used to get a broad-level picture of the world.

Keywords: geography, earth, maps, globes
