let's rock and roll
what is the cycle called that different forms of rocks go through over time?
Rock cycle
evidence of an animal that lived long ago
A fossil
when small pieces of rock are moved from one place to another
erosion
The centermost layer of the earth made of hot solid metal
inner core
molten rock inside earth's surface. When it cools it forms igneous rock with crystals inside.
Magma
what type of rock forms from great heat and pressure?
burried under
Process that breaks down rock. It can be chemical or mechanical
weathering
The centermost layer of the earth that is liquid metal
DOUBLE JEOPARDY!!
outercore
what is magma that flows outside of a volcano onto earth's surface called? when it cools it forms igneous rock.
Lava
what type of rock is formed from sediments that have been deposited into new places
sedimentary rock
what landform was therized due to the findings of fossils of the same animals in different places on earth?
Pangea
This is a type of precipitation that is mixed with a greenhouse gas that can weather away certain types of rock.
DOUBLE JEOPARDY!!
Acid Rain
the thickest and spongest layer of the earth
mantel
one who studies earth and its history
geologist
what type of rock is formed when magma or lava cools and hardens
igneous rock
what type of scientist studies fossils?
Paleontologist
when there is a great amount of water that causes a landslide what is happening?
Water erosion
The thinnest layer of the earth that contains the continents and ocean floor
crust
what two things change earth's surface quickly?
volcanoes and earthquakes
what is the difference between lava and magma and what type of rock do they form?
Lava is found on top of earths surface and cools quicker than magma that is found underneath earth's surface. Magma forms crystals because of this. Both magma and lava form igneous rock.
what type of fossil is a hardened rock of an actual body part such as a bone or tooth?
true or body fossil
when plant roots, water, or wind break down rock overtime it is called
mechanical or physical weathering
what happens when tectonic plates move?
changes occur on earth's surface
when small pieces of rock settle at the bottom of rivers, lakes or streams or on landforms
depositon
