Lecture #8: Volcanism and volcanic hazards
Intra-plate volcanism- Mantle plume and hot-spot volcano.
Volcano- An erupting vent through which molten rock surfaces. A mountain built from
eruptions. Pipeline for molten rock to travel. Connects pool of molten

Uniformitarianism-physical processes that operate in the modern world also operated in
past, at roughly the same rates, and these processes were responsible for forming geologic
features preserved in outcrops

Lecture #3: Earths spheres
Lithosphere- Hard parts of Earth. It largely consists of rocks and minerals. Divided into
three parts: crust, mantle, core. Iron, oxygen, silicon. Most iron is found in the core.
Cryosphere- Water in solid form (snow/ice)
Lecture #4: Life, Evolution & Fossils
Classification- The placing of organism into groups. Based on their similarities and
differences. Prevents improper IDs.
Homologous traits- Shows similarities in mammals.

Crust- Rigid rock. Thickness is about 5-100km. Stiff, brittle, breaks under pressure.
Asthenosphere- Lower part of the upper mantle. Two types- continental and oceanic.
Lithosphere- Lithospheric mantle plus crust. Move
