Q

Heterogenous v Homogenous

A

Homo: solutions in which the individual components are uniformly distributed throughout the mixture

What is chemical weathering?
Changes to the atomic structure of matter through hydrolysis, oxidation, reduction, hard action, carbonation, and solution
26
What is physical weathering?
It occurs when minerals and rocks are broken down by mechanical methods such as abrasion, crystallization, wetting and drying, or pressure release
27
What is biological weathering?
This occurs when an organism psychical or chemical agents disintegrate rocks or minerals.
28
What are igneous rocks ?
-Found under or above ground. -These are the result of the lava cooling above ground -Ex: Granite and Obsidian
29
What are sedimentary rocks?
Results from wind or water breaking or wearing down small pieces of Earth that often settle to the bottom of rivers, lakes, and oceans
30
What are metamorphoic rocks?
Rocks changing or morphine into other kids of rocks. Igneous or sedimentary rocks heated under tons of pressure change into this
31

32
What is conduction?
Transfers heat between substances that are in direct contact with each other
33
What is convention?
Transfers heat through the movement of molecules in water or air and forms cool and warm currents of winds due to differences in heat absoption
34
What are the main types of clouds?
Stratus - Flat, light and dark (stable weather or rain expected soon) Cumulus - Fluffy, solid, and light (good weather) Cirrus - Thin and wispy (changes in weather expected) Cumulonimbus - Tall, thick, and dark (Heavy rain, thunderstorm even)
35
