Water/States of Matter
What is the density of water?
1g/mL
What is the shape of the Earth?
Sphere or Oblate Shperoid
What igneous rock makes up most of the continental crust?
Granite
Earths crust is broken up into sections called
Tectonic plates
What are minerals?
Geological substances that are made from elements.
All substances are densest in their solid state. What is the exception?
Water
What are the three major parts of earth
Lithosphere- Solid Crust
Hydrosphere- Liquid(ocean)
Atmosphere-gas
What is the thickness of the crust, and where is it thinnest?
The thickness varies from 5km to 60km, and it is the thinnest under the ocean.
What are the three varieties of plate boundaries?
Convergent, divergent, and transform
Are fossil fuels minerals?
No because they are organic materials.
What are the states of matter?
Solid, liquid, gas
What does the angle of Polaris show us?
In any location north of the equator, you can find the latitude by using the angle of Polaris above the horizon.
What is the difference between continental and oceanic crust?
Continental crust is made mostly of granite, it is thicker but less dense, and it is less felsic while oceanic crust is made mostly of basalt, it is thinner and denser, and is more mafic
What kind of boundary can be found at a mid ocean ridge?
Divergent plate boundary
How are igneous rocks formed?
They are formed by the cooling of magma. The speed of cooling can differentiate between different types of igneous rocks.
What qualities does mass have?
Mass, volume and density
Which part of Earth consists of the most water?
What is the density of the continental crust?
2.7g/cm3
What are the three types of earthquake waves?
P-waves, s-waves, and surface waves
What causes mineral banding in metamorphic rocks?
Light and dark bands are caused by alternating bands of mafic and felsic mineral.
How does phase change affect volume and density?
Solid->Liquid->Gas: volume increases, density decreases
Gas->Liquid->Solid: volume decreases, density increases
Which direction do longitude and latitude go in?
Longitude goes North to South, while latitude goes East to West
What is the mantle divided into?
Asthenosphere-upper portion of the mantle also called plastic mantle
Stiffer mantle
Outer core
inner core
Is rock older nearer or farther from a mid ocean ridge?
farther
How does cooling speed affect igneous rock grain size?
The faster the cooling, the smaller the grain size
