In order, what are the seismic waves that effect an area that has been hit by an earthquake? a.) Primary waves, Surface waves, Secondary waves b.) Secondary waves, Surface waves, Primary waves c.) Surface waves, Primary waves, Secondary waves d.) Primary waves, Secondary Waves, Surface waves
d.) Primary waves, Secondary Waves, Surface waves.
Convection currents help drive the process of plate tectonics. Which part of the geopshere do these currents occur at. a.) Outer core b.) Crust c.) Lithosphere d.) Asthenosphere
d.) Asthenosphere
If you are attempting to determine the main type of rock found in an area, which of Earth's systems are you studying?
Geosphere
What is the term for the large, rigid pieces of earths crust? a.) faults b.) sediment c.) mountain d.) tectonic plates
d.) tectonic plates
True or false, The magnitude of an earthquake can range from less than one to at least 20? What is the tool used to measure the power of an earthquake?
1-10, ritcher scale
What is the area called where one plate (oceanic) is forced below another plate (continental? What type of boundary occurs here?
Subduction zone; convergent boundary
The process of the rock cycle take place in which location? a.) deep inside the geopshere b.) in the atmosphere c.) on Earth's surface d.)
d.) Both A and C on the earth surface (lava cooling and deep inside)
Name all four of Earth's Systems and what their roles are.
Atmosphere-Air/Weather/Protection Geosphere- Solid Part of the Earth Biosphere- All living things Hydrosphere- Water
What is the theory of plate tectonics? and why is it important?
Earth's surface is broken into large, rigid, pieces that move with respect to each other. This process is powered by convection currents in the earths mantle. The theory is important because it explained much about how Earth changes over time.
What is a fault?
A fault is a crack in the crust where movement occurs.
What type of boundary is known to cause earthquakes?
Transform
What are the two types of crust that make up the earth's surface? Which type is thinner/thicker? Which is more dense/less dense
Continental and Oceanic Crust. Oceanic crust is thinner but more dense while Continental is thicker but less dense.
Which of the following is part of the geosphere? a.) a cloud b.) a plant c.) a deer d.) a cliff
a cliff
What are 2-3 pieces of evidence that were discussed that helped support the theory of plate tectonics?
Fossil Evidence/ Apparent fit of Continents
What are the three main types of volcanoes?
Cinder Cone, Shield, and Composite (strato-volcanoes)
How are volcanoes formed?
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
