What are the three types of rocks?
What is metamorphic, igneous, and sedimentary?
100
Its existed for about 4.5 billion years
What is Earth?
100
What is the rock cycle?
What is the rock cycle is the set of natural procesess that form, change, break down, and re-form rocks.
100
Why are sedimentary rocks more common at the Earth's surface?
What is the process that forms sedimentary rocks occurs at the Earth's surface.
100
These rocks are found in Earths crust
What are metamorphic, igneous, sedimentary rocks?
200
What is a rock?
What is a rock is a naturally formed soild that is usually made up of one or more types of minerals.
200
The surface of soil is usually covered with leaves, broken branches, and fallen trees. This layer keeps the ground damp by preventing too much water from evaporating.
What is "litter."
200
How can a sedimentary rock become a metamorphic rock?
What is you apply heat and pressure to the sedimentary rock and it becomes a metamorphic rock.
200
The three major types of rock
What is Igneous, Metamorphic, Sedimentary?
200
Some of these rocks have large crystals while others have none at all.
What are igneous rocks?
300
Rock composed of layers of sediment.
What is "sedimentary rock."
300
A hot, liquid solution of dissolved minerals that cools to form igneous rocks.
What is "magma."
300
How is igneous rock formed?
What is it is formed when molten rock cools and becomes solid.
300
This rock is formed by heat and pressure
What is Metamorphic?
300
There are this many layers in the Earth.
What is four layers?
400
What are three kinds of metamorphic rocks, and how do they form?
What is quartzite, slate, and marble. Quartzite forms when sandstone becomes quartzite, slate forms when shale becomes slate, and marble forms when limestone becomes marble.
400
When stubble from the previous crop, including the roots, is left in the ground, and new seed is planted into the old stubble. No plough is used.
What is "zero tillage."
400
How does one type of rock change into another type of rock?
What is Natural processes change each type of rock into other types. Igneous rock is formed when molten rock cools and become solid. Sedimentary rock forms as pieces of older rocks, plants, and other loose materials get pressed and cemented into rock. Metamorphic rock forms as heat or pressure or both cause older rocks to change into new types of rock.
400
The main difference between the three types of rock.
What is how they form?
400
The surface of soil is usually covered with leaves, broken branches, and fallen trees. This layer keeps the ground damp by preventing too much water from evaporating.
What is "litter."
500
Tell me three kinds of igneous rocks and how they form.
What is three types of igneous rocks are granite rocks, pumice rocks, and scoria rocks. Granite rocks form from slowly cooling pockets of magma under the Earth's surface. Pumice rocks form when lava cools quickly above ground, leaving small pockets of air in the rock. Scoria rocks form when lava cools quickly above ground, leaving little pockets of air in the rock.
500
This layer of soil is solid and unbroken rock.It may be under soil, but it is still subject to biological weathering from plant roots.
What is "bedrock."
500
This is the average depth of the Grand Canyon.
What is one mile?
500
These are all rocks but not all rocks are these
What are minerals?
500
A series of layers that is created as soil develops.
What is "horizons."
