Layers of the Earth
What layer of the earth is broken into several different pieces?
Crust
What kinds of geologic events are caused by transform boundaries?
earthquakes
What properties should you use to identify a mineral if you don't know what it is?
color, streak, hardness, and special properties like magnetism, fluorescence, and reactive with acid
You are a rock that formed when lava cooled after a volcanic eruption. What kind of rock are you?
igneous rock
What is the thinnest layer of Earth?
The crust
Which layer of the earth is completely liquid?
Outer Core
What is subduction? (What kinds of plates are involved, and what happens to each of them?)
An oceanic plate runs into a continental crust plate at a convergent boundary and the oceanic crust gets pushed down underneath the continental crust because it is more dense.
How do you test the streak of a mineral?
Use the mineral like a piece of chalk on a hard surface (like a ceramic tile) and observe what color of mineral powder is left behind
You are a rock in the oceanic crust, formed by pressure squishing together the grains of sand that had collected there. What kind of rock are you?
Sedimentary Rock
What is our Elf's name?
Sprinkle Bottom
Which layer of earth is soft and gooey, but not completely melted?
Mantle
How do the plates move in each of the 3 tectonic plate boundaries?
Convergent: plates move crash into each other; Divergent: plates move apart; Transform: plates slide past each other in opposite directions
What is a mineral?
An inorganic solid formed on or in Earth that is composed of atoms in a crystalline shape
You are a very dense and heavy rock with wavy layers. How did you form?
Heat and pressure (you are a metamorphic rock)
In what town is Camp Cody located?
Freedom, NH
Which layer makes rock SLOWLY rise and sink in circles because of convection?
Mantle
What 3 different observations led scientists to believe that the continents are moving?
1. Fossil evidence (same plant/animal species found on different continents that now have different climates) 2. Continents are similar shapes that fit together like puzzle pieces (South America and Africa, for example) 3. Mountain ranges are made of the same rock layers on different continents (the Appalachian Mountains match a mountain range in Scotland, for example)
Which objects should you use (in order) when testing a mineral's hardness?
fingernail, copper penny, steel nail
What kind of rock often has fossils inside of it?
sedimentary rock
What is Geology?
The study of Earth's history and the processes that form it
Why is the inner core solid even though it is the hottest layer?
There is too much pressure from all of the layers on top of it for it to melt
What kinds of events can happen at a convergent boundary?
Mountains, Subduction, and/or Volcanoes
All ______ are made out of 2 or more different kinds of minerals.
Rocks
How does sediment form?
weathering and erosion
What is Mr. Holt's favorite holiday?
Christmas
