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

Global climate change, tectonic activity, asteroid impacts, and large volcanic eruptions are all factors that have led to ______
horsena [70]

Global climate change, tectonic activity, asteroid impacts, and large

volcanic eruptions are all factors that have led to Loss in the fossil record.

Climate change is the modification in the earth climate as a results of

humans and other interaction with the earth.

Climate change causes damages to earth morphology and indirectly

causes loss of fossil records.

Tectonic activity such as earth quakes and volcanic eruption are mostly

due to the interaction of earth lithospheric plates. This plates either diverge

or converge and causes modification of the earth lithosphere. This

modification causes loss of fossil record.

Asteroid are rocky object in the exosphere that cause massive impact in

the earth when they hit it.  This event that destroys the earth causes loss in

fossil record.

Volcanic eruptions is when lava(semi liquid) and gas are released through

a volcano to the earth surface. They cause massive destruction to the earth

and invariably cause loss of fossil records.
