Answer:

A. The angle of repose is the steepest angle at which unconsolidated sediments can sit without slipping downhill

Explanation:

The angle of repose is the steepest angle at which unconsolidated sediment can be piled without sliding downward. The angle is also known as critical angle . At this angle the unconsolidated sediments are at the verge of slumping . The angle between the surface of the piled sediments and the horizontal surface is the angle of the repose. At this angle the unconsolidated sediments have reached it limit of accommodating more materials unless it will slump downward.

The make up of the unconsolidated sediments can affect the angle of repose as rounded and fined gained rocks cannot be piled as rough texture d rock materials. The angle of repose can also be affected by the amount of solvents in the sediment. Various rocks sediments possess different angle of repose. Same sediment material can possess different angle of repose if the water contents varies .Example, the angle of repose for sand varies depending on the water contents. The true statement is option A.

The picture above illustrate the angle of repose.

Listed below are the names, spectral types (in parentheses), and approximate masses of several nearby main-sequence stars. Rank
Kruka [31]

Answer:

Rank of the stars from shortest to longest distances:

Barnard's Star (M4)

61 Cygnia A (K5)

Alpha Centauri A (G2)

Sirius (A1)

Spica (B1)

Explanation:

The habitable zone, also known as the circumstellar habitable zone, is the range of distances from a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.

The location of a star’s habitable zone is dependent upon its luminosity, which is the amount of light emitted by an object in a unit of time, because a star’s luminosity increases with time; and also the star's mass.

The inverse square law of light brightness can be used to determine the extent of the habitable zones for different luminosity stars with the formula:

star boundary = Sun boundary × squareroot[(star luminosity)/(Sun luminosity].

Why do geographers use different terms to discuss these groups.
Over [174]

Answer:

Explanation:

Un geógrafo es un científico e investigador cuyo campo de estudio es la Geografía, el estudio de la superficie terrestre, tanto en su composición física como en las actividades e interrelaciones humanas que ocurren en ella. Estudian la superficie de la Tierra (geosfera) de acuerdo con sus estructuras espaciales, los procesos que tienen lugar y sus funciones (interacciones entre los geofactores). Trabajan entre las ciencias naturales, las ciencias sociales y las humanidades y se engloban en el grupo de profesiones que manejan información espacial.

Los geógrafos son generalistas debido a la amplitud de su campo de estudio y ser la Geografía una ciencia transversal, lo que le facilita integrarse con otros profesionales en equipos pluridisciplinares. Su forma de trabajar es a la vez analítica y normativa: los geógrafos empleados como planificadores se guían por la comprensión moderna de la planificación y brindan soluciones para los problemas entre los humanos y el medio ambiente.

this sets up a pressure gradient between tropics and the ITCZ, which causes surface air to flow from the _____ toward the ______
Trava [24]

Answer:

<u>Lower latitudes to higher latitudes i.e low pressure to high pressure.</u>

Explanation:

  • As the pressure gradient is a force that is derived from the lower latitude to the upper latitudes in the form of pressure systems and the winds belts that arise from ITCZ zone thus there is an upwelling of warm and hot air from this region and goes upwards to the polar regions and in between from a convective cycle.
  • There is a characteristic of this zone in the form of a vigorous thunderstorm over large bodies of the ocean. All this heating is derived due to the sun's rays fall directly over the equator.
  • ITCZ being the doldrum zone or zone of calms sets the surface air to fly pass creating a frontal situation of the hot and cold air mass to interact and create eddies in the oceans.
