How does the Theory of Plate Tectonics explain volcanoes and

earthquakes?

How does the Theory of Plate Tectonics explain volcanoes and earthquakes? The earth’s crust is broken into plates. These plates are moved by

convection currents. Melting plates create earthquakes, plates that move after being

temporarily stuck cause earthquakes.

What makes the plates move?

What makes the plates move? Convection currents

Plates move about 2 centimeters a year. There are 100 cm in a meter and 1000 m in a km. How

many years would it take for a divergent

boundary to widen by 1 km?

Plates move about 2 centimeters a year. There are 100 cm in a meter and 1000 m in a km. How

many years would it take for a divergent

boundary to widen by 1 km?

100 cm/meter * 1000m/km = 100,000 cm / km.

100,000 cm divided by 2 cm per year = 50,000 years for the plates to diverge 1 km.

1 km x 1000 m x 100 cm x 1 year = 50,000 years 1 km 1 m 2 cm

What does plate tectonics do to the biodiversity of the earth?

As plates move, animals must adapt to the new climates, form new species or go extinct.

What causes erosion? Wind, water, plowing, worms, gophers

vehicular/foot traffic, mining, roads, build homes, storms, etc..

The rate of erosion is related to the surface area of the rock.

Which of the following metamorphic rocks would erode the fastest:

Rock A with a mass of 400 grams and a surface area of 50 cm2.

Rock B with a mass of 400 grams and a surface area of 500 cm2.

The rate of erosion is related to the surface area of the rock.

Which of the following metamorphic rocks would erode the fastest:

Rock A with a mass of 400 grams and a surface area of 50 cm2.

Rock B with a mass of 400 grams and a surface area of 500 cm2 is fastest because the more area that is exposed, the more the wind, rain, roots and snow can weather away.

An earthquake on the Ring of Fire registered 4 on the Richter Scale. A

later in earthquake centered in Pakistan registered an 8 on the Richter Scale.

How many times stronger is the Pakistan earthquake compared to the

Ring of Fire Earthquake?

An earthquake on the Ring of Fire registered 4 on the Richter Scale. A

later in earthquake centered in Pakistan registered an 8 on the Richter Scale.

How many times stronger is the Pakistan earthquake compared to the

Ring of Fire Earthquake?Each level on the Richter Scale is 10 times greater than the last. 8 is 4 places bigger than 4 on the scale, so the Pakistan earthquake is 10*10*10*10 = 10,000 times greater than the Ring of Fire earthquake.

What is an aqueduct?

What is an aqueduct? A

system of canals or pipes used to transport fresh water from a

location that has lots of water to

one that has less

water.

What is an estuary and how can aqueducts impact an estuarine

environment?

What is an estuary and how can aqueducts impact an estuarine environment? Estuaries

are formed where salt water meets fresh water. Aqueducts remove fresh water from a river

and thus make the estuary more saline which reduces the species richness of the estuary.
