Earth Materials & Features :: Geology :: Earth Science

Aligned with the Texas Essential Knowledge and Skills (TEKS) for 5th grade science. SCI.5.7A.A I can explore the processes that led to the formation of fossil fuels and sedimentary rocks. SCI.5.7B I can recognize how landforms such as deltas, canyons, and sand dunes are the result of changes to Earth's surface by wind, water, and ice.
STUDY

geology
The study of the earth.
inner core
The solid, iron-nickel center of the Earth. This is the hottest layer.
outer core
The liquid, iron-nickel outer center of the Earth.
mantle
The thick, molten, rocky layer between the crust and the core.
crust
The thin, solid, rocky outer layer of the Earth.
tectonic plate
A large piece of the Earth's crust and upper mantle that slowly moves on top of a boiling mantle.
igneous rock
Rock made when melted rock (magma/lava) cools.
sedimentary rock
A type of rock formed by layers of sediments that were squeezed and stuck together over a long time
metamorphic rock
Rock made from other rocks that change through heat and pressure.
rock cycle
The never ending cycle of rocks changing from one type to another.
constructive force
Force that builds up the earth.
destructive force
Force that takes down the earth.
weathering
The breaking up of earth materials into smaller pieces.
erosion
Moving sediments by water, wind, or glaciers.
deposition
Dropping sediments down in a new location.
sediment
Pieces of broken up rock.
glacier
A large body of ice that moves slowly, usually downhill
landform
Features of the earth's surface, such as plains, continent, mountain, canyons, hills, plateau, or valley.
delta
Triangular piece of land formed from water depositing sediment at the opening of a river
canyon
A deep valley with very steep sides - often carved from the Earth by a river (moving water)
sand dune
Hill or a ridge made of sand. Dunes are shaped by the wind, and change all the time
valley
Low place or land between two mountains
fossils
The remains or imprint of a previously living organism.
fossil fuel
Source of energy made from dead plants and animals that have been placed under extreme heat and pressure. Examples include oil, coal, and natural gas.
