Geography

asambeis [7]3 years ago

Answer:

While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale describes the earthquake's magnitude by measuring the seismic waves that cause the earthquake. The two scales have different applications and measurement techniques.

Explanation:

Mercalli Scale Richter Scale

Measures The effects caused by an earthquake The energy released by an earthquake

Measuring Tool Observation Seismograph

Calculation Quantified from observation of the effects on earth’s surface, humans, objects and man-made structures Base-10 logarithmic scale obtained by calculating logarithm of the amplitude of waves.

Scale I (not felt) to XII (total destruction) From 2.0 to 10.0+ (never recorded). A 3.0 earthquake is 10 times stronger than a 2.0 earthquake.

Consistency Varies depending on distance from epicenter Varies at different distances from the epicenter, but one value is given for the earthquake as a whole.

You have been tasked with sorting the rock samples shown into three categories, with two rocks in each category. What attribute
fredd [130]

I would sort them into the categories of metamorphic rock, sedimentary rock, and igneous rock.

Igneous rocks are made from the cooling and solidifying of lava or magma. Pumice is one of these rocks, it's made from lava being thrown out of volcano, and rapidly cooling. Obsidian and granite the other igneous rocks in the list.

Sedimentary rocks are made from the sedimentation of smaller particles. Coquina limestone is one of these - it's made from the sedimentation of the shells of dead animals.

Metamorphic rocks are rocks which are created by extreme heat and pressure. Essentially, they used to be a different kind of rock, and now they're metamorphic rocks. Gneiss and soapstone are both metamorphic rocks.

So here are your final answers:

Igneous: Granite, Obsidian, Pumice

Sedimentary: Coquina limestone

Metamorphic: Gneiss, Soapstone

Hope this helped!
