2. A 260 em cylinder container was used to collect an undisturbed soil sample. The container and soil weighed 403 g when dried.
sineoko [7]

Answer:

The Bulk density = 1.3 g/cm³

the porosity of the sample is 132 cm³

Explanation:

Given:

Volume of cylinder = 260 cm³

Mass of container and the soil = 403 g

Mass of the empty container = 65 g

Thus,

The mass of the soil is = 403 - 65 = 338 g  

Now,

The Bulk density = \frac{\textup{Mass}}{\textup{Volume}}

or

The Bulk density = \frac{\textup{338 g}}{\textup{260}}

or

The Bulk density = 1.3 g/cm³

also,

average particle density for mineral soil is usually given as 2.65 g/cm³

i.e the air present in the given soil sample has reduced its density from 2.65 g/cm³ to 1.3 g/cm³

The mass of the whole sample = Volume × Density

= 260 × 2.65

= 689 gm

but,

The actual mass of the dry sample = 338 g

thus,

Mass of air in the sample = 689 - 338 = 351 g

Therefore,

the volume of 351 g soil = \frac{\textup{mass defect of soil}}{\textup{density of soil}}

=  \frac{\textup{351}}{\textup{2.65}}

= 132.45 cm³

so the porosity of the sample is 132 cm³

Which statements describe the relationship between history and geography?Geography affects history, but history has no geographi
rjkz [21]

Answer:

Geography affects History.

Geography is the setting of History story's.

Geography influence History.

Explanation:

GEOGRAPHY is the study of the physical features of the earth and its atmosphere, and the interaction between human beings and physical environment. While HISTORY is the record of human activities in the old times comprising civilizational marches in different periods spent in the lap of time.

History is mostly shaped and enriched by prevalent geographical settings.

The climate aspect of geography also largely influences the history and its characteristics. Geographical features like mountains and plains have had equally profound impact on human history. Mountains invariably influence the history of many countries.
