Layers of the Earth
This is the thinnest layer of the Earth, as well as the coolest.
What is the Crust?
What are Convection Currents?
This is a physical force that won't change the type of rock, just it's appearance. It's caused by temp. change, ice or growing plants.
What is Physical Weathering?
The process that changes rocks into other types of rocks is called?
What is the Rock Cycle?
This is often found in Sedimentary rock, and is usually in the form of shells, footprints, bones or leaf prints.
What are Fossils?
This is the thickest layer of the Earth, and is made of flowing molten rock.
What is the Mantle?
When tectonic plates run into each other mountains, trenches and volcanoes form when tectonic plates for this.
What is Convergent or Converge?
This force creates chemical reactions between air, water and minerals inside the rock. A common example of this is Acid Rain.
What is Chemical Weathering?
What are:
1. heat and pressure
2. weathering and erosion
3. compaction and cementation
?
This is a combination where two or more substances have been combined, but it hasn't changed either substance, and therefore can be separated back into their original substances. Examples of this include trail mix, sand and water, and cereal and milk.
What are Mixtures?
This is the third layer of the Earth, which is made of liquid iron and nickel, and is even hotter than the Mantle.
What is the Outer Core?
This happens when tectonic plates move apart from each other, causing magma to rise up and cool in the ocean creating new land.
What is Divergent, or Diverge?
This process occurs when weathered material (like rocks) is moved from one area to another. This usually happens with the assistance of wind, water, gravity, etc.
What is Erosion?
This type of rock is formed by the cooling down of magma, can be light or dark in color and usually won't have any layers of fossils inside of them.
What is Igneous rock?
These pieces of rock, clay, sand, etc. are created (broken off) by Physical Weathering.
What is Sediment?
This is the fourth layer of the Earth, which is made of solid iron and nickel, and is the hottest layer.
What is the Inner Core?
What is Transform?
When eroded rocks sediments arrive at their new location and are left behind it is known as this.
What is Deposition?
This type of rock is formed through extreme heat and pressure, rarely has fossils within it, can alternate through light and dark colors, and has crystals inside of it.
What is Metamorphic?
This is the difference between a Solvent and a Solute.
What is that Solvents are substances that typically breakdown and dissolve another substance, while a Solute is the substance that is typically being broken down by the Solvent?
What are Convection Currents?
What is a circular motion in the Mantle of cooling and heating melted rock caused by thermal energy?
This plate boundary, found in the Pacific Ocean, is where a lot of earthquakes and volcanoes could and have occured.
What is the Ring of Fire?
What are some things that humans can do to fight against Erosion?
What are:
1. Build Retaining Walls--human made walls that block rocks and soil from being taken away.
2. Plant vegetation, as the roots can hold the ground together.
3. Terracing--build layers into the ground, which can limit the movement of rocks and soil
This rock type is formed through compaction of cementation, often contains fossils and layers within.
What is Sedimentary?
This is a mixture of where two or more substances have been mixed together, and Solutes and Solvents are involved. This mixtures can not be undone once the substances have been combined. Examples include energy drinks, sugar and water, and baking ingredients combined.
