compacted and cemented together
developed through a long process that starts with weathering and ends with lithification
process when rocks are physically and chemically broken down by water, air, and living things
rock cycle is powered by heat from earth's interior. internal source is heat
external source is weathering and the movement of weathered materials = produce sedimentary rocks (igneous and metamorphic)
what powers the rock cycle? Internal source and External source
process by which sediments are squeezed together by the weight of overlying materials driving out water
takes place when dissolved minerals are deposited in the tiny spaces among the sediments
Assuming a rock doesn't melt in the process of heating and pressure what type of rock will form?
Draw the rock cycle.
Include all processes and contents. Begin with magma at the top of the cycle.
coarse grained texture
What type of texture does a rock have when it forms from a large mass of magma that solidifies slowly far below Earth's surface?
Lava that cools so quickly that ions do not have time to arrange themselves into crystals will have what type of texture?
Large crystals and small crystals
The igneous classifications of
coarse-grained and fine-grained mean...
weathering, erosion, deposition, compaction and cementation
What is the order of the five processes involved in sedimentary rock formations?
clastic sedimentary rock
What type of sedimentary rock is formed by weathered particles of rocks and minerals?
rock was formed near a beach or stream bed
What does it suggest when there are ripple marks in sedimentary rocks?
Clastic and chemical (and also a sub-category biochemical)
The classifications of sedimentary rock are...
Where is the energy source found that drives the processes that form igneous and metamorphic rocks?
The rock cycle is driven internally by heat from Earth's interior, and externally by energy from ...
Foliated = crystals combine and form visible bands
Non-foliated = non-banded texture
What are the two classifications of metamorphic rock and describe each.
The peaks of the Himalayas used to be an ocean floor
Why have fossils of marine animals been found buried in the Himalayas?
water, wind, ice (glaciers), gravity
What are the major erosional agents that can pick up, transport, and deposit the products of weathering?
