There are nearly 300 million passenger cars in the U.S. The average gas mileage is 25 MPG (miles per gallon) and each car is dri
Natasha_Volkova [10]

Answer:

1.0236 billion metric tons

Explanation:

Given Parameters

Number of cars = 300000000

Average gas mileage per car = 25 MPG

Average distance covered by a car in one year = 10000 miles

CO2 Emission = 8.53 kg/gallon

Derivations from the given parameters,

If the average gas mileage per car is 25 MPG, then the volume of fuel consumed by a car in a year is:

<em>10000 miles ÷ 25 MPG = 400 gallons </em>

The CO2 emission for one car in a year is:

<em>400 gallons × 8.53 kg/gallon = 3412 kg or 3.412 metric tons (note: 1000 kg = 1 metric ton) </em>

The CO2 emission for 300000000 cars in year is:

<em>3.412 metric tons × 300000000 = 1023600000 kg = 1.0236 billion metric tons </em>

raketka [301]

Answer:

D. the arrangement of mineral grains into a foliation

Explanation:

Due to the tectonic activity of the terrestrial lithosphere, igneous and sedimentary rocks formed in certain environments and under precise environmental conditions, can be subjected to new conditions (essentially pressure and temperature). Under the new conditions, and frequently under the action of tectonic stresses (linked, for example, to the formation of mountain ranges), pre-existing rocks are transformed texturally, structurally and mineralogically into a solid state, giving rise to metamorphic rocks. Its fundamental characteristic is to present blastic texture (i.e., solid state recrystallization), and in cases of deformation, anisotropic factories.

The petrographic characteristics of these rocks are especially complicated, given the solid state transformation processes that they have suffered, usually accompanied by intense deformation. Due to the gradual nature of metamorphic (and deformational) transformations, the characteristics of this type of rock also range from igneous or sedimentary to purely metamorphic.

<u>Foliation </u>

The term foliation (foliatus: leaf-shaped) refers to any planar (almost flat) arrangement of mineral grains or structural features of the interior of a rock. Although there is foliation in some sedimentary rocks and even in a few types of igneous rocks, it is a fundamental characteristic of rocks that have undergone regional metamorphism, that is, rocky units that have folded and deformed greatly. In metamorphic environments, foliation is caused, ultimately, by the compressive efforts that shorten the rock masses, causing the mineral grains of pre-existing rocks to develop parallel or almost parallel alignments. Examples of foliation are the parallel alignment of minerals with planar habit and / or elongated minerals; the parallel alignment of mineral particles and flattened edges; the compositional bandeado where the separation of dark and light minerals generates a laminar appearance, and the blackboard when the rocks easily separate into thin and tabular layers along parallel surfaces. These different types of foliation can be formed in many different ways, such as:

1. Rotation of elongated or planar mineral grains towards a new orientation.

2. Recrystallization of minerals to form new grains that grow in the direction of the preferred orientation.

3. Changes in shape in equidimensional grains to elongated shapes that align in a preferred orientation.

What is the difference between external &amp; internal migration
Salsk061 [2.6K]

External migration takes place for educational or economic reasons as well, but often, it is politically motivated. An international migrant is someone who moves to a different country. Simply, internal migration refers to the movement of people within a country.
