Minerals
Name 7 ways that you can identify a mineral
color, streak, luster ,hardness, breakage, cleavage, fracture
Which crust is more dense
Oceanic crust
What are the three types of rocks
igneous rock, sedimentary rock, metamorphic rock
Who was the guy who created the Contenetal drift theory
Alfred Wengers
Hypothises
a possible explanation for an observation that can be tested by scientific investigations
What makes a mineral a mineral
Its crystallization
Found in nature not made from humans
periodic table patterns formed
Identify The 4 Earth systems
Atmosphere, Geosphere, Biosphere, Hydrosphere.
How do you make a sedmintary rock in to a metamorphic rock
heat and pressure
What is Pangaea
name given to a supercontinent that began to break 200 million years ago
Mass
The amount of matter in an object
what is the hardest And softest Mineral on the Mohs Hardness scale
Dimaond and Talc
How does the Geosphere and Biosphere work together
They make habitats
How do you Identify a rock
Grain size
shape
chemical composition
What are the 3 types of Plates and what do they do
Transform- 2 plates slide agianst each other
Divergent- 2 plates separate from each other
Convergent- 2 plates collide and form mountion ranges
Crust
The brittle, rocky outer layer of earth
What are the two types of minerals in halite
Sodium and Cholrlne
What spheres does the mantle have in it
Lithosphere, Asthenosphere, Meosphere and the convection currents
How do metamorphic rocks form in igneous rock
They melt then magma heats and cools then crystalization turns hard.
What are 4 clues that support the Continental drift theory
Puzzle pieces, Climate clues, Rock clues, and Fossil clues.
Streak
The color of a minerals powder
What is a mineral
is a naturally occurring inorganic solid with a definite chemical composition and an orderly arrangement of Adams or ions
How did the Earth form
1. Material from a nebula come together. 2. Thermal energy softens materials 3. gravity pulls out the bumps 4. most denses particles pulled to the center 5. The Least dense particles shape the crust
What is the rock cycle
How rocks form and change from on type to another
WHat is seafloor spreading
Its when to divergent- plates create a mid ocean ridge and magma rises forming new crust
Luster
the way a mineral reflects or absorbs light at its surface
