Rock Cycle Scavenger Hunt
13. What is solid rock?
Settled pieces of rocks and minerals at bottom in water over very long time (perhaps millions of years), form into Solid rock.
6. How are Igneous rocks formed from erupted volcano?
The magma cools down and harden, either on the Earth's surface or somewhere within the crust. This hardened magma or lava is called igneous rock.
24. What is the effect of pressure and heat on Sediment rock?
5. Under the high pressure and heat, Sedimentary rocks are Metamorphosed into a Metamorphic rock and the cycle starts again.
8. How is Igneous Extrusive rock formed?
Igneous-Extrusive rock is formed when lava cools quickly on the earth's surface.
11. In which categories Intrusive rocks are classified?
Intrusive rocks can also be divided into two categories based on color: Dark colors black-brown-green - Gabbro Light colors white-gray-pink - Granite
18. Give the examples of Metamorphic rocks.
Other examples of Metamorphic rocks include marble, anthracite, soapstone and schist.
Write the name of three major types of rocks?
There are three major types of rocks: Metamorphic, Igneous and Sedimentary.
4. How are Igneous rocks formed?
Igneous rocks are formed by volcanoes.
20. What is the very first step of the rock cycle to form rock?
1. Melted rock or magma is sent to the earth's surface by a volcano. It cools and forms an Igneous rock.
21. Which events do convert rocks into small sediments?
2. Weather or a river or other events slowly breaks up this rock into small pieces of sediments.
22. After sediment hardens, what is formed?
3. As sediment builds up and hardens over the years, a Sedimentary rock is formed.
17. How is slat or gneiss formed?
A Shale and Sedimentary rock can be changed or Metamorphosed into a Metamorphic rock such as slate or gneiss.
1. Give the definition of rock.
A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
7. Give the two examples of Igneous rocks.
Examples of Igneous rocks include basalt and granite.
14. Write examples of Sedimentary rocks.
Examples of Sedimentary rocks are shale, limestone, and sandstone.
9. In which categories Extrusive rocks are classified?
Extrusive rocks can be divided into two categories based on color: Dark colors black-brown-red - basalt - obsidian Light colors white-gray-pink - rhyolite
10. How is Igneous Intrusive rock formed?
Magma cools slowly over millions of years, so large crystals are formed. It is called IGNEOUS-Intrusive rocks.
15. How is Metamorphic rock formed?
Metamorphic rocks are formed by great heat and pressure.
16. Where is Metamorphic rock found in Earth?
Metamorphic rocks are generally found inside the Earth's crust where there is enough heat and pressure to form the rocks.
2. How are rocks classified?
Rocks are classified based on how they are formed, on their composition and texture.
19. What is the rock cycle?
Rocks are constantly changing which is called the Rock cycle.
12. How is Sedimentary rock formed?
Sedimentary rocks are formed by years and years of sediment compacting together and becoming hard.
23. How does sediment rock end up in Earth's crust?
4. Slowly the Sediment rock gets covered with other rocks and end up deep in the Earth's crust.
What is called magma or lava?
When a volcano erupts, it spews out hot molten rock called magma or lava.
