Igneous rocks Study guides, Class notes & Summaries

Igneous Rocks - ANSWER-These rocks were originally liquid, below the earth's crusts and are formed by lava and magma. Metamorphic Rocks - ANSWER-These types of rocks are formed by heat and pressure. Sedimentary Rocks - ANSWER-A river flows through a canyon and picks up a bunch of silt. That sediment and silt runs downstream and deposits where the river ends. When that material gets to the beach, it sits there. Over millions of years, _____ form. Earth's tilt on its axis. - ANSWER-Mr. ...

The ability of a mineral to resist scratching is called - Answer- hardness The breaking of a mineral along definite planes is called - Answer- cleavage The two most abundant elements in the earth's crust are - Answer- oxygen and silicon Which of the following internal crystalline structure of minerals does not have three axes at right angles to one another? - Answer- monoclinic Ore minerals contain - Answer- a useful metal or nonmetal that is easily extracted The two most importa...

ASVAB – Latest Update (2022/2023) Graded A+ Geology The study of the nature and composition of the rocks and material that make up the Earth, how they were formed, and the physical and chemical processes that have changed earth over time Mineral a naturally occurring, inorganic solid that has a crystal structure and a definite chemical elements Organic compounds Carbon- containing remains of decomposed plant or animal matter Mineraloids Minerals that lack a defined crystalline structure. 3...

Earth Science Lab Final (Answered) Complete Verified Solution Noncomformity 1) Younger sedimentary rocks on top of older metamorphic or intrusive igneous rocks 2) Imply period of uplift of deeply buried rocks Three types of uncomformities angular uncomformity, disconformity, and noncomformity Radiocarbon dating Using the carbon-14 isotope to date very recent events (Half-life of carbon-14 is only 5,730 years) (Only useful for dating events from historic past and very recent geolog...

Fault correct answers A plane in rock along which movement occurs Liquefaction correct answers - A process by which water-saturated sediment temporarily loses strength and acts as a fluid - When the ground is a poorly consolidated sediment or sedimentary rock with water in the pore spaces, shaking can cause the sediment to become like quicksand. - Dry/wet sand analogy Fractional Melting correct answers A mixture of molten and solid rock when the entire rock does not have the same melt...

Physical geology vs. Historical geology - Physical geology deals with materials and processes that make up the Earth, Historical geology is applying chronology to events in Earth's past Relative age - Determination that something is younger or older than something else Absolute Age - Precise measurement of how much time has passed since something was created or modified Fossils - Remains, traces, or other indications of life Principal of Original Horizontality - Sediment is deposited in l...

tidal hypothesis : Theory that the solar system started with a near collision of sun and large star. Few astronomers believe this theory. condensation hypothesis : solar system began with rotating clouds of dust and gas. Condensation happened in center to form sun, and smaller parts of clouds formed. More astronomers believe in this idea. Core : Outer core- liquid; inner core- solid. Very dense in center. Believed that core is 80% iron. Helps heat oceans. Mantle : Surrounds core. ...
