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.
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? 1 km x 1000 m x 100 cm x 1 year = 50,000 years 1 km 1 m 2 cm or 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.
What does plate tectonics do to the biodiversity of the earth?
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.
Which type of sediment has the least permeability to water? clay Which type of sediment has the largest size?
Which type of sediment has the least permeability to water? clay Which type of sediment has the largest size? Sand
Which type of sediment has a high cation exchange capacity? Clay
How long does it take to make soil? Hundreds to thousands of years.
What season will have the thickest O horizon in a deciduous forest in the northern hemisphere? (O horizon)
What season will have the thickest O horizon in a deciduous forest in the northern hemisphere? Fall (O horizon)
Acids ______________ pH and limestone ________ pH. Limestone (calcium carbonate) being dropped in a lake.
Acids decrease pH and limestone increases pH. Limestone (calcium carbonate) being dropped in a lake.
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.
