Earth's Spheres
Name all of the spheres of Earth...
Hydrosphere, Biosphere, Geosphere, and Atmosphere
In order, name each layer of Earth from outermost layer to innermost layer.
Crust, mantle, outer core, and inner core.
What are the 3 types of rocks?
Sedimentary, Metamorphic, and Igneous
Ture or false: Rocks cannot change into other types of rock.
False
What interaction is taking place when a tornado destroys the landforms in the surrounding area?
The interaction is between atmosphere because of the tornado, and the geosphere because of the landforms.
What makes up Earth's Hydrosphere?
All of Earth's water.
What layer is the thinnest layer of Earth?
The crust
How are sedimentary rocks formed?
Sedimentary rocks must undergo compaction and cementation.
Weathering (breaking down of rock) and erosion (the movement of rock)
A student is debating what kind of materials to use for the mantle of her Earth's layers model. She is deciding between water in a bag, a marble, slime, or graham crackers. What material should she use?
She should use the slime, because it's a semi-solid consistency.
What makes up Earth's Geosphere?
All of Earth's landforms.
What is the layer that is a semi-solid (putty like) and is the thickest layer of Earth composed of mostly iron and magnesium?
The mantle
How are igneous rocks formed?
Igneous rocks are formed when molten rock cools and solidifies.
When a metamorphic rock reaches the mantle, it will melt from the hot temperature. What do we call this molten rock under Earth's surface?
Magma
A student places crayons in foil, and places it on a hot plate. The student melts the wax of the crayon, and then allows it to cool until its a solid. What type of rock would be represented in this situation?
An igneous rock
A deer is drinking water from a small pond. What interaction is taking place between Earth's spheres?
The deer is a living thing so that's biosphere, and it's interacting with the hydrosphere because the pond is water on Earth.
What layer is completely liquid nickel and iron?
The outer core
How are metamorphic rocks formed?
Metamorphic rocks are formed from lots of heat and pressure.
What processes have to happen for an igneous rock to become a sedimentary rock?
The rock being weathered into sediment then compaction and cementation.
What kind of material would you consider to be most accurate to represent the outer core of Earth, jello, orange soda, a tennis ball, or crushed up Oreos ?
Orange soda
A volcano erupts causing all the grass in the area to be burnt. What two spheres are interacting in this situation?
The geosphere and the biosphere are interacting, because the volcano represents the geosphere and the grass represents the biosphere.
The inner core
What kind of igneous rock is created when it forms outside on the surface of Earth?
Extrusive Igneous Rock
Shale is an sedimentary rock, but over time it can change and form Slate, a metamorphic rock. What process would allow shale to undergo this change?
The shale would have to have extreme heat and pressure to turn into slate.
This layer of Earth has the hottest temperature and is the most dense layer...What is it?
The Inner Core
