Bas_tet [7]4 years ago
4 0

Explanation:

Given parameters:

Distance of the seismic station from Blue mountain lake = 1200km

Unknown:

Time  = ?

Solution:

To solve this problem, we must know that velocity is the displacement divide by time:

              Velocity = \frac{Displacement}{time taken}

Since we are looking for time, lets make it the subject of the expression;

        Time taken = \frac{displacement }{velocity}

velocity of the wave is a consant = 6km/s

Time taken = \frac{1200}{6} = 200s

Which of the following could become metamorphic rocks?
BigorU [14]

<u>Answer: </u>

Neither rock A nor B could become metamorphic rocks.  

<u>Explanation: </u>

  • Magma is the molten rock under the surface hardens into igneous rock. This rock breaks down over time under the process of weathering.
  • These pieces of "igneous rocks" are cemented together with other bits of rocks to form sedimentary rocks.
  • These rocks get buried under the geological processes like earthquakes. Now, coming in contact with high temperatures and magma, these rocks get changed into metamorphic rocks.
  • So, from option A, igneous rock is formed. When combined with rock B and other rocks, sedimentary rocks are formed.
  • Metamorphic rocks are formed in the next process. Therefore, neither of the two rocks could become "metamorphic rocks".

Ipatiy [6.2K]

Answer:D. Lake Michigan has a moderating effect on Milwaukee's temperatures.

Explanation: Milwaukee is the fifth largest city in mid Western United States of America,it is located in the State of Wisconsin.

Lake Michigan has a great Impact on the Temperature of Milwaukee as it helps to drop the Temperature up to about 4degrees.

Milwaukee is located along the shores of lake Michigan, which has helped to calm down Milwaukee's Temperatures.Lake Michigan does this by attracting most of the impact of the sun and releasing water Vapor through evaporation to the Atmosphere,this will in turn help to reduce the climatic Temperature around Milwaukee.
