Fossils
What type of rocks are most of the fossils found to date?
Sedimentary rocks!
What is the definition of weathering?
The process that breaks down rocks and other materials at Earth's surface.
What is it called when two plates slide past each other?
Transform Boundary
Which part of Earth's interior is inferred to have convection currents that cause tectonic plates to move?
Mantle
What is Mrs. Zunino's soccer jersey number?
11
Why be number one once when you can be it twice?
The deeper the layer of rock the fossil is in the older the fossil is.
The more shallow the layer of rock the fossil is in the younger the fossil is.
What is the difference between mechanical weathering and chemical weathering?
Mechanical weathering is the grinding away of rock by other rock particles carried by wind, water, or ice.
Chemical weathering changes the actual chemical structure of the rock by a chemical reaction.
When a rift valley forms in the center of a mid ocean ridge, what is the type of crustal plate boundary?
Divergent
What do scientists correlate the movement of tectonic plates being driven by?
Convection currents in the mantle.
What is Mrs. Zunino allergic to?
Rude people (ach-oo).
What two methods can scientists use to determine a fossil's age?
Relative Age Dating and Absolute (Radioactive) Age Dating
How does chemical weathering occur?
When rocks are chemically broken down or dissolved by substances in the environment.
Explain subduction in a convergent plate boundary AND draw a picture!
Answers vary but must include definition and a picture showing two plates colliding and the denser plate subduing (going below) underneath the lighter plate.
Explain convection currents in Earth's mantle.
The outer core heats the magma in the mantle, causing it to rise to the crust. It cools and becomes dense, then sinks back down.
How many living pets does Mrs. Zunino have?
Four!
Two dogs, a cat, and one hermit crab named Rachel.
If fossils of marine organisms are found in an area that is now dry land, what can you infer about the geography about that dry land?
That area of dry land was once an ocean at some point in the past.
When rock materials ERODES off of a mountain and is DEPOSITED into a valley, what happens to the TOTAL amount of rock, sand, and sediments? Does it increase, decrease, stay the same, or can you not determine the total amount?
It remains the same until the wind moves or disturbs the rock, sand, and sediments.
What is the difference between a Primary wave and a Secondary wave in an Earthquake?
Continental Drift is the theory that the continents were once all joined together in a super landmass called Pangea. Over time the continents drifted apart through plate tectonics.
What's Mrs. Zunino's favorite day of the week?
Wednesday!
How do scientists determine the Absolute Age of a fossil?
Radioactive dating; scientists compare the half-life of a sample to the amount of the element that it breaks down into.
List three examples of how water causes erosion.
Examples:
1. Water in a river carrying small particles from one location to another
2. Runoff from rainfall picks up sediment on the ground and moves it from one location to another
3. Glaciers can pick up boulders and other sediment from higher elevations to lower elevations
What type of landmass could be caused by two tectonic plates converging?
Mountain
What is one of the biggest differences between oceanic crust and continental crust?
Oceanic crust is more dense than continental crust!
What is Mrs. Zunino's favorite drink from Starbucks?
Chai tea latte
