Earths layers
What is happening as you go further down the earth's layers in terms of temperature, pressure, and depth?
What is increasing?
What are the 5 characteristics of a mineral?
1. naturally occurring
2. inorganic
3. solid at room temperature
4. regular crystal structure
5. defined chemical composition.
What are the 3 major types of rocks?
What are igneous, Metamorphic, and sedimentary rocks?
What are the key features of the crust, mantle, outer core, and inner core?
The crust is the hard outermost layer of the earth. The mantle is part liquid part solid and is the one with convection currents. The outer core is completely liquid. The inner core is solid due to extremely high pressure.
Describe the physical properties of minerals: streak, luster, color, density, crystal structure, cleavage, fracture, hardness and special properties
What is the color of a mineral's powder, the way light reflects off a mineral, , ,the way a mineral breaks along a flat surface, ...
How do they form?
Metamorphic= heat+pressure
Igneous= when magma cools
Sedemintary= when sediments compact
What are convection currents, where and how do they occur?
Convection currents are when due to heat in the mantle currents start to form.
