Spherical Earth
Can a small object have more mass than a larger object?
Yes a small object can have more mass than a larger object because mass is determined by the amount of density.
Which of Earth’s layers are the densest?
Inner Core
What landform region is Edgemont, SD in?
Interior Plains
What is a mineral?
Naturally occurring, inorganic solid with a definite chemical composition and an orderly arrangement of atoms or ions
What is the way a mineral reflects or absorbs light at its surface called?
Luster
Why does Earth exert a greater gravitational force on you than other objects do?
The distance between us and Earth is less than other objects
How does oceanic crust differ from continental crust?
Oceanic crust differs from continental crust because oceanic crust is more dense than continental crust.
What is a topographic feature formed by processes that shape the earth?
Landform
What are the two main families of rock-forming minerals?
Silicate and nonsilicates
Describe Hematite's luster
Metallic luster and very shiney
What factors affect the strength of the gravitational force between objects?
The mass and the distance between them
What evidence indicates that the outer core is liquid?
Earthquake waves
Which of Earth's major types of landforms covers most of Earth's surface?
What is Plains
Identify the five major characteristics of a mineral
- Naturally occurring
- inorganic
- solid
- definite chemical composition
- an orderly arrangement of atoms or ions
How are streak and color related?
Streak is the color of a mineral in powdered form
How did the Earth develop is spherical shape?
Earth developed its spherical shape from the gravity pulling in the irregular bumps on the surface
What are the interior layers of Earth?
Upper mantle, Lower mantle, outer core, inner core.
Describe a plateau
Areas of low relief and high elevation
Does Basalt or Andesite cool more quickly?
Basalt
Why can't the mineral quartz be classified based on color alone?
Quartz can be many different colors such as clear, white, smokey gray, purple, orange or pink.
Identify Earth’s Major Systems
o Atmosphere- Layer of gases surrounding Earth.
o Geosphere- Earth’s entire solid body.
o Biosphere- all living organisms on Earth.
o Cryosphere- Frozen water on Earth.
o Hydrosphere- liquid water on Earth
Compare the lithosphere and the asthenosphere.
The lithosphere is the Earth’s rigid outer layer, composed of the crust and the uppermost solid mantle, while the asthenosphere is a hotter more plastic, semi-fluid layers of the mantle found directly beneath the lithosphere

How does a vein of gold form?
Hot solutions flow into cracks and carry large concentrations of dissolved solids.
Identify all the properties used to classify an unknown mineral.
Density, Cleavage and Fracture, Hardness, Streak, Luster, and Color
