Soil Test Review

Which layer of Earth is composed primarily of iron and nickel?

• The core
• The crust
• The mantle
• The lithosphere

Subduction

• Is the reason similar fossils appear on both sides of the Atlantic
• occurs when one plate passes under another
• occurs when oceanic plates diverge and form volcanoes
• is the process in transform boundaries that results in earthquakes

The Hawaiian islands were formed

• At a hot spot
• At a transform fault
• at a mid-ocean ridge
• At a divergent plate boundary

How far will a plate travel in 60,000 years if it moves at net rate of 25 mm/yr?

• 3000m
• 1,500m
• 1,500mm
• 12,000m

Which rock is formed at high temperatures and pressures?

• Sedimentary
• Extrusive igneous
• Metamorphic
• Intrusive igneous

Earthquake epicenters are often at

• Transform boundaries
• Divergent boundaries
• Hot spots
• Convergent boundaries

Acid precipitation directly causes:
I: Erosion
II: Physical Weathering
III: Chemical Weathering

• I and III
• I, II, and III
• I only
• II only

What are the five primary soil formation factors?

• Altitude, climate, parent material, latitude, organisms
• Climate, parent material, pH, organisms, topography
• Parent material, climate, pH, latitude, altitude
• Climate, parent material, topography, organisms, time

Which is the correct order of soil horizons starting at the surface?

• Hummus, lots of hummus.  It's going places, I swear.  Invest in hummus. Do it.
• O, A, E, B, C
• O, E, A, B, C
• E, A, B, O, C

What type of soil would be best for a man-made pond, where the goal is to have as little leakage of water as possible?

• Mostly sand
• Equal amounts of sand, silt, and clay
• Mostly silt
• Mostly clay
