Earth's Materials
What element are diamonds made of?
Carbon - heat and pressure of Earth's interior caused carbon atoms to join together to form diamonds
What are volcanoes?
Volcanoes are structures formed around a hole in Earth's crust that releases magma
What is my name?
Miss Somaiy!
All ____ are made up of mixtures of minerals.
Rocks
The transport of sediment by wind, water, or gravity is _____?
Erosion
True or False: Diamonds are the hardest naturally occurring material
True! Diamonds are so hard that only other diamonds can be used to cut them.
What are the names of the set of coordinates for each location on Earth's surface?
hint: begins with L
Latitude and Longitude
When is your Unit 2 Exam?

What are the three categories of rock?
Igneous, Metamorphic, and Sedimentary
What is weathering?
The breakdown of rock into smaller pieces. There are two kinds: chemical and mechanical.
Luster falls into two categories: ______ and ______
Metallic and Nonmetallic
Volcanoes occur because Earth's crust is broken into drifting slabs of rock called ___ ___
Tectonic plates!
True or False: Steve Harvey is the host of Jeopardy
False! He's the host of the game, Family Feud
How does igneous rock form?
Igneous rock forms when either magma or lava cools and hardens.
______ weathering occurs when rocks are broken down by physical forces without any change in their chemical structure
Mechanical
True or False: Minerals are naturally occurring
True! Minerals occur naturally, meaning they do not require humans to exist
True or False: the majority of landforms on Earth's surface have formed because of the movement of the tectonic plates.
True! This is the reason we have mountains, valleys, and volcanoes
True or False: The TV show, Jeopardy!, is still on air
True! As of 2023, the game show entered its 40th season making it one of the longest-running game shows.
How does sedimentary rock form?
Sedimentary rock forms from layers of sediment (sand, soil, clay, gravel, etc.) that are built up in one location over time
_______ weathering occurs when chemical reactions change the composition of rocks, changing into a new substance with different properties
Chemical
What does it mean for something to be inorganic?
Inorganic means it is NOT the product of something living or that was once alive.
For example, shells or leaves would be considered ORGANIC since they came from something that was once alive
What are the three plate boundaries?
Convergent - two plates move toward one another, perpendicular to the fault line
Divergent - two plates move apart from one another, perpendicular to the fault line
Transform - when two plates slide past each other in parallel
Where did Miss Somaiy go to college?
Baylor University - Sic em' Bears!
How is metamorphic rock made?
A chemical reaction where one type of rock is changed by pressure or heat into a new type of rock with different properties.
What is the process that forms, breaks down, and re-forms rock from one category to another?
