Igneous
This is the molten rock found below earths surface?
What is Magma
Tiny pieces of rock, sand, shells etc. is called what?
Sedimentary
Metamorphic rocks can be made from what 3 different types of rocks
What is sedimentary, metamorphic or igneous
When sediments go under compacting and cementing processes they become____
What is sedimentary rocks
This is the molten rock found above earths surface?
What is Lava
The final 2 processes that turn sediments into sedimentary rocks?
What are compaction and cementation
The lines/layers of a metamorphic rock look different than the lines of a sedimentary rock because
What is metamorphic rocks have wavy layers due to heat
When igneous, metamorphic and sedimentary rocks go under weathering and eroding they become
What is sediments
Igneous rocks are categorized as _____or_____ depending on where the molten rock cooled?
extrusive and intrusive? Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet
What is the difference between weathering, erosion and depesotion?
What is weathering breaks down the rock, erosion carries it away, and deposition drops the sediment off
______is the movement of minerals into layers or bands on a metamorphic rock?
Folation
Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance. Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned.
what is the processes that turn metamorphic rocks into sediments called?
Weathering and eroding
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
______ igneous rocks have larger crystals than the other kind of igneous rocks
Intrusive
The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow.
What is when water expands and weathers rock?
What are parent rocks?
they are rocks or minerals that are pushed together to make a new metamorphic rock
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
An example of heat and pressure is when sedimentary rock shale becomes slate when heat and pressure are added. The more heat and pressure you add, the further the rock metamorphoses until it becomes gneiss. If it is heated further, the rock will melt completely and reform as an igneous rock.
Vesticular
is a small cavity in an aphanitic or glassy igneous rock, formed by expansion of a bubble of gas or steam during solidification of the rock
