Earth's Spheres
This sphere is all of the frozen water on Earth.
What is the cryosphere?
What is sedimentary rock?
It has a pure substance throughout.
What is a mineral?
Where two plates meet
What are plate boundaries?
Lines that run around the globe and tell you how North or South you are from the equator.
What is lines of latitude?
This part of the Earth includes the mantle, crust, and core.
What is the geosphere?
Metamorphic rocks form by
What is heat and pressure in the Earth's mantle
Crystalline Structure
What is a repeating pattern of atoms?
What occurs at plate boundaries?
Earthquakes and volcanoes
Lines that run up and down on a globe and measure East or West from the prime meridian.
What is longitude?
What is interaction between hydrosphere and geosphere?
Rocks that cool quickly.
What are small crystals? What is extrusive igneous rock?
Describe the 5 characteristics of minerals?
Describe what forms and how a divergent boundary forms
Divergent boundaries are two plates spreading apart and they form new crust.
What are contour lines?
What is cryosphere and geosphere?
Describe how a igneous rock can become a sedimentary rock. Be specific with steps.
1. Igneous rock gets weathered by wind, rain, or water.
2. It forms sediments.
3. The sediments are carried through erosion. 4. Sediments get compacted over time.
5. Those sediments then get compacted and layered into a sedimentary rock.
What are the 2 environmental conditions for crystals to form?
Heat and water
The rising and falling of mantle due to differences in temperature and densities that cause the plates to move.
What are convection currents?
You are going to measure the height of plants that receive different amount of water. To see which amount of water is best to increase the plant growth. Name the dependent and independent variable.
Dependent Variable: Plant Growth / Plant Height
Independent Variable: The amount of water
The air temperature is increasing which is causing animals to move more North to higher latitudes. What two spheres are interacting?
Atmosphere and Biosphere
Describe how the rock cycle is a physical change and a chemical change.
When rocks melt as they get subducted. The atoms rearrange and form a new substance ( a new rock) as they are melted. They are also a chemical change due to chemical weathering. Rain is slightly acidic and can cause rocks to break down and atoms to rearrange. Carbon Dioxide can be formed from limestone. Weathering can be a physical change such as frost wedging.
Describe how crystals to form different sizes.
If crystals cool slowly than they can be big in size, if they cool quickly they can be small in size. They can be weathered due to wind and rain causing them to be small.
What is subduction?
0 degrees latitude.
