Chapter 2.5, Aside from Earth, which other planet shows evidence of plate tectonics? O a. Mercury O b.Venus O c The Moon d, Mars
ki77a [65]

Answer:

b.Venus

Explanation:

  • Like earth, venus does not have any major faults or folds or rift valleys ridges on its surface thus it does not have any global tectonic or plates of rock in rotation.
  • Being a terrestrial planet, the seismic data collected from the moment of inertia and possible due to the planet plates are too rigid to move but the phases of volcanoes have been found in the craters in addition mountains, and valleys are commonly found on rocky lands points out to some degree of tectonics present under the planet.
  • Also, the size and structure of the plan tell about its core, mantle and crustal zones. Also, venus is supported to have a magnetic field not as strong as the earth which is induced by the ionosphere and Solar Winds.

Identify the true statement. Choose one: A. The angle of repose is the steepest angle at which unconsolidated sediments can sit
Margarita [4]

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.

Does the map above consider the hazard only for an earthquake with a focus at the centre of the strong shaking zone on the map?
jeka94

Answer:

An earth-quake is a geo-hazard.

Explanation:

  • An earthquake is a Geo-hazard that is characterized by violent shaking of the ground by the release of seismic waves such as P and S waves.  
  • The focus is the place in the crust where the earthquake originates and the point directly that is above the focus is the hypocenter. The hypocenter experiences strong shaking and can be seen by the impact of seismic waves on the map.
