Magma ( melted rock inside the earth) bubbles up to the surface.
Lava (magma on the surface) exits through a vent (opening).
Lava cools, solifies, & builds up to form a mountain. (VOLCANO)

A. Load amount of material carried by stream.
(Faster rivers carry more load.)

Chapter 7 -10 Weathering and Mass Movement
Soil = combination of small rock fragments and organic material.
Weathering = process that breaks rocks into smaller fragments to make soil.
Can be affected by:
1) Composition of the rock (Soft rock weathers
Naturally formed material made of minerals
and other materials.
Building blocks of the earth.
Provide metal & mineral products.
Most are made of the same 20 minerals.
Classified into one of three
I. Soil formation
A. 100-1000 years = 1 cm of soil
B. Factors affecting soil formation
1. Parent material type
2. Climatic factors
a. Temperature changes increase
b. Moisture speeds up soil production

Section 1 Earthquakes
What causes earthquakes?
Plates slide past each other creating friction.
The friction builds up until the plates slip.
Focus = source of earthquake (inside earth)
Epicenter = point directly above earthquake o
