Seismic waves are sent through the earth during earthquakes, and those
energy waves are what cause the ground to shake as they travel through
it.Seismic waves travel at different speeds when they pass through
different types of material, so by studying seismograms, scientists can
learn a lot about Earth's internal structure.Body waves are seismic
waves that travel through Earth's interior, or its 'body.' Surface waves
are seismic waves that travel through Earth's surface.Surface waves are
important, but they don't provide much information about what happens
below the surface. For this, we need to study body waves so that we can
see what Earth's 'body' is like.
There are two types of body waves, called P waves and S waves. P
stands for primary waves because these waves travel the fastest and are
detected first. S stands for secondary waves because these are slower
than P waves, arriving second on the seismogram.
Answer:
it is a good way
Explanation:
It is a good way to gather demographic information because it's very accurate. Censucount.org says that "The Census Bureau reported a net national overcount of 0.01% in 2010" which means they are only off by a little, but still effective. THe demographic information is then used to decide where to distribute the funds and taxes for schools, public areas, supermarkets, etc.
the answer is B. Stratovolcano
Stratovolcano is composed by one layer of hardened lava, volcanic Ash, and Tephra
These volcanoes are identified by their periodic explosive eruption, spitting highly viscous lava that could spread in a far distance
South Africa is the most stable country south of the Sahara
