The Structure of Earth
These are the 7 continents of planet earth.
This is the reason you cannot dig through the earth to the other side.
What is "because it is so hot underneath the earth's crust that you would die"?
This is some of the ways that Earthquakes can effect humans.
What is destroying buildings or other structures, causing injury or death due to falling objects or buildings, causing Tsunamis and potentially causing fires (due to broken gas/electric lines)?
This is the difference between magma and lava.
What is "Magma is molten rock that is underground, lava is molten rock on the earth's surface"?
This is the process that forms igneous rocks.
What is the Lava/Magma cooling down to become solid?
These are the 4 layers that make up planet earth in order from hottest to coldest.
These are the 3 major oceans of earth.
What are the Atlantic, Pacific, and Indian Oceans.
This is the difference between the epicenter and the focus of an earthquake.
What is the focus is the point below the earth's surface where the earthquake originated and the epicenter is the point directly above the focus on the earth's surface?
These are the 3 things that come out of a volcano.
What are "ash, gas, and lava (molten rock)"?
This is the difference between intrusive and extrusive igneous rocks.
What is extrusive rocks are formed from lava (on the surface of earth) and intrusive rocks are formed from magma (inside the earth)?
This is how the position of the continents was different 220 million years ago.
What is "all the continents were squashed together in a super continent called Pangaea"?
This is the name and description of the type of tectonic plate boundary that causes mountains to form.
What is "collision boundary - where two continental plates converge (meet)"?
This is the name and description of the type of tectonic plate boundary that causes earthquakes.
What is a conservative boundary where two tectonic plates move past each other in different directions or at different rates?
This is the bowl shaped indentation at the top of a volcano.
What is a crater?
This is the 4 step process that forms sedimentary rocks.
What is
1. Weathering and erosion (small bits of rock (sediments) breaking off and being transported)
2. Deposition (sediments fall so the sea floor)
3. Compaction (sediments and crushed together)
4. Cementation (water is squeezed out)
This is the phenomenon that caused the continents to move to new positions.
What is the movement of Tectonic Plates.
This is an example of sedimentary rock.
What are sandstone, limestone, chalk
This is the meaning of the word "seismic".
What is "related to earthquakes"?
These are the names of the two types of tectonic plate boundaries that are likely to cause volcanoes, along with their descriptions.
What are
1. Destructive boundaries (where an oceanic plate and a continental plate converge or meet and the oceanic plate is pushed under the continental plate)
2. Constructive boundaries (where two plates diverge or move apart)
?
This is the process that forms metamorphic rocks.
What is heat and pressure due to movement of tectonic plates changes igneous or sedimentary rocks into a new type of rock?
This is the temperature (in degrees celcius) of the earth's core.
What is 5,200 degrees celcius?
This is an example of metamorphic rock.
What is marble? (gniess, schist, quartzite)
This is a break or fracture in the ground caused by the movement of tectonic plates (often the location of earthquakes)
This is 1 example of intrusive igneous rock and 1 example of extrusive igneous rock.
What are:
Intrusive: Granite
Extrusive: Obsidian, pumice, scoria, basalt
This is the thing that the freeze thaw cycle, acid rain, waves repeatedly hitting the a rocky shoreline, and tree roots growing into a crack in a cliff all have in common.
What is "they are all examples of weathering"?
