Rock Cycle
6th Grade Science Chapter 10
Question | 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 |
