Answer |
| Type of rock that forms when molten magma from within Earth cools and solidifies |
igneous rock |
| Magma that reaches Earth's surface is called ____. |
lava |
| Type of rock that forms when particles of rock and other materials are compacted and cemented together. |
sedimentary rock |
| Type of rock that forms when heat and great pressure beneath Earth's surface is applied to igneous or sedimentary rock. |
metamorphic rock |
| "metamorphic" means |
a change of form |
| Rocks are classified as metamorphic, sedimentary, or igneous based on ___________. |
how they were formed |
| Geologists study |
the physical conditions of the Earth, such as the temperature of material in its interior |
| Over millions of years, the three different kinds of rock continuously change from one kind into another in this process called the ___________. |
rock cycle |
| Could this statement be true? Igneous rock is eroded to form metamorphic rock. |
No.
If igneous rock eroded, it would then form sedimentary rock (not metamorphic rock). |
| Could this statement be true? Metamorphic rock melts to form sedimentary rock. |
No. If metamorphic rock melted, it would then form igneous rock (and not sedimentary rock). |
| Could this statement be true? Igneous rock is heated and squeezed to form metamorphic rock. |
Yes. Any sedimentary or igneous rock that is heated and squeezed can turn into metamorphic rock. |
| What type of rock is formed when broken pieces of any kind of rock are deposited into layers and cemented together? |
sedimentary rock |
| Erosion and deposition on Earth's surface forms what kind of rock? |
sedimentary rock |
| Magma cooling beneath Earth's surface or lava cooling on Earth's surface forms what kind of rock? |
igneous rock |
| Heat and pressure beneath Earth's surface form what kind of rock? |
metamorphic rock |
| When heat and pressure change the minerals in a rock, what kind of rock is formed? |
metamorphic rock |
| When lava cools on Earth's surface, what kind of igneous rock is formed? |
extrusive igneous rock |
| When magma cools beneath Earth's surface, what kind of igneous rock is formed? |
intrusive igneous rock |
| The innermost layer of the Earth is called the |
inner core |
| The uppermost part of the mantle is part of Earth's ______________. |
lithosphere |
| Rocks produced when pieces of other rocks, plant and animal matter, or dissolved minerals collect to form rock layers are called |
sedimentary rock |
| What type of rock can melt to form magma? |
any type, sedimentary, igneous, or metamorphic |
| What kind of rock can weather and erode to form sediment? |
any type, sedimentary, igneous, or metamorphic |
| When __________ compacts and cements, sedimentary rock forms. |
sediment |
