|---|---|---|---|---|---|
| Rocks have properties that can be | observed, tested, and described.
🗑
|
||||
| Composition, grain size and textural features, color, and the presence of fossils help with | identification.
🗑
|
||||
| Rocks move and change over time due to | heat and pressure within Earth.
🗑
|
||||
| Rocks move and change over time due to | weathering, erosion, and deposition at the surface.
🗑
|
||||
| Rocks can change | from one type to another.
🗑
|
||||
| sedimentary rocks | layers of sediment cemented together
🗑
|
||||
| igneous rocks | melted and cooled, e.g., lava and magma
🗑
|
||||
| metamorphic rocks | changed by heat and pressure.
🗑
|
||||
| Scientific evidence indicates Earth is ancient — approximately | 4.6 billion years old.
🗑
|
||||
| Fossils provide | information about life and conditions of the past.
🗑
|
||||
| Earth is composed of | four concentric layers
🗑
|
||||
| The crust is composed primarily of | rocky material.
🗑
|
||||
| The mantle is composed mostly of | molten rock.
🗑
|
||||
| The innermost layers are composed mostly of | iron and nickel.
🗑
|
||||
| Pressure and temperature | increase with depth beneath the surface.
🗑
|
||||
| Earth’s thermal energy causes | movement of material within Earth.
🗑
|
||||
| Large continent-size blocks are called | plates
🗑
|
||||
| Most earthquakes and volcanoes are located at | the boundaries of the plates (faults).
🗑
|
||||
| Plates can move together | convergent boundaries
🗑
|
||||
| Plates can move apart | divergent boundaries
🗑
|
||||
| Plates can slip past each other horizontally | transform boundaries, also called strike-slip or sliding boundaries
🗑
|
||||
| Geological features in the oceans (including trenches and mid-ocean ridges) and on the continents (mountain ranges, including the Appalachian Mountains) are caused by | current and past plate movements.
🗑
|
||||
| Rocks and other materials on Earth’s surface are constantly being broken down both | chemically and physically.
🗑
|
||||
| The products of weathering include | clay, sand, rock fragments, and soluble substances.
🗑
|
||||
| Materials can be moved by water and wind | eroded
🗑
|
||||
| Materials can be deposited in new locations as sediment | deposition
🗑
|
||||
| Humans | have varying degrees of impact on Earth’s surface through their everyday activities.
🗑
|
||||
| With careful planning, | the impact on the land can be controlled
🗑
|
||||
| Ring of Fire | The area of tectonic plates with the most amount of active volcanoes in the world.
🗑
|
||||
| Mountains | These are formed when two convergent plates come together and force land to move upward.
🗑
|
||||
| Lava | This is magma outside of the Earth.
🗑
|
||||
| Pangaea | This is the theory of a "super continent", when the Earth was a single landmass.
🗑
|
||||
| Coffee | This is what college students use to keep good grades.
🗑
|
||||
| Mr. Holzshu | This is someone who was old enough to live on Pangaea.
🗑
|
||||
| Mariana Trench | This is the deepest valley in the world, deep in the Pacific Ocean.
🗑
|
||||
| 22 Miles | The average thickness of the Earth's crust.
🗑
|
||||
| mantle | The thickest layer of the Earth.
🗑
|
||||
| Earthquakes | Caused by shifting of tectonic plates.
🗑
|
||||
| Transform Faults | Their movement causes earthquakes.
🗑
|
||||
| Earth's new crust | Comes from magma cooling when it reaches the crust.
🗑
|
||||
| volcanoes | Where magma from the mantle comes from.
🗑
|
||||
| Trenches | When convergent plates come together and push downward, these form.
🗑
|
||||
| Mountains | When convergent plates come together and push upward, these form.
🗑
|
||||
| Mid-ocean ridges | When divergent plates come apart, and magma seeps up, forming new crust.
🗑
|
||||
| faults | These are the boundary lines between tectonic plates.
🗑
