What do you observe happens when a p wave travels from a solid to a liquid?

Answers

1- It depends on the incident angle at which the P-wave hits the liquid. Using snells law, a portion of the energy is converted to an S-Wave, a portion of it ir reflected, but the majority of the energy just disappears ( it is absorbed into the liquid ) since P-waves do not travel through liquids.2- it spreads out making the sound travel faster than it does in air3- P-waves move up and down4- S-waves move side to side5- P-waves are pressure waves, or longitudinal waves. The motion is in the direction of the wave. These waves travel through solids and liquids.S-waves are shear waves, or shaking waves. The motion is perpendicular to the wave direction. These waves cannot travel through liquids.An earthquake produces both P and S waves and by monitoring the arrival (or non-arrival) of P and/or S waves around the Earth we can infer a liquid component to the core.

Name the polar and tropical air masses that affect U.S. weather. Describe the pattern of movement across the continent and patterns of precipitation associated with warm and cold fronts.

Answers

Answer:

The answer to this question can be defined as follows:

Explanation:

In the cold surface, the air is defined by polar weather systems and relatively warm surface air masses. Its masses throughout the polar vortex are very cold.  

and the 5 air masses, that impact the United States in such a normal year: continental polar, Continental Arctic, continental tropical, marine polar, maritime tropic. It influences the 5 Coastal in the USA for the continental plates, and the pattern of movement can be defined as follows:      

  • influenced both by the West  
  • switch to the east from the west  
  • SINKS Cold Air  
  • Cold, rain and storms, steeper slope

What positioning system may give coordinates as decimals?

Answers

Decimal degrees. Such degrees are a good alternative to using degrees, minutes, and seconds (DMS). Similar to latitude and longitude, the values are bounded by ±90° and ±180° respectively.

ANSWER:

Units of measurement will help to measure the decimal degree for identifying latitude and longitude.

EXPLANATION:

  • Coordinate system is described as a set of rules and measure due to which it grants access over integrating over a certain place or area.
  • The coordinates system does help to display the various terrain, lands, mountains and other structure of an area.
  • In geographical information system, it is considered to be two types coordinate system in which one study is made by taking global coordinates and projected coordinates.
