Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories. ... Other, less common minerals include calcium, magnesium, and sulfur. The biotic and abiotic factors in the soil are what make up the soil's composition.
Facts about soil: Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.
What does soil do to our earth: Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

Explicación:
¿Qué significa que un automóvil viaje con una rapidez de 45 [(Km.) ⁄ (Hr.)]?
Si se dice que un automóvil viaja a una velocidad de 45 km / h, entonces el automóvil cubre una distancia de 45 km en una hora. 45 km / h es una derivación de la velocidad de desplazamiento obtenida de la relación;
Velocidad = distancia / tiempo
Velocidad = 45 km / 1 h.
Distancia = velocidad × tiempo
Distancia = 45 km / h × 1 h
Distancia = 45 km
Por lo tanto, a esa velocidad, se cubrirá una distancia de 45 km por cada hora que se mueva.
A material that resists the flow of electrons is called an insulator.
Answer:
1. The best definition of refraction is ____.
a. passing through a boundary
b. bouncing off a boundary
c. changing speed at a boundary
d. changing direction when crossing a boundary
Answer: D
Bouncing off a boundary (choice b) is reflection. Refraction involves passing through a boundary (choice a) and changing speed (choice c); however, a light ray can exhibit both of these behaviors without undergoing refraction (for instance, if it approaches the boundary along the normal). Refraction of light must involve a change in direction; the path must be altered at the boundary.
