Geology Chapter 3 EXAM REVIEW WITH COMPLETE & VERIFIED SOLUTIONS Why does magma rise toward the Earth's surface? - Answer ️️ -Because it is less dense than the material around it What is required for an igneous rock to weather? - Answer ️️ -It must be exposed at the surface of the earth What is the most common place for sediment to be deposited? - Answer ️️ - oceans What is the difference between "magma" and "lava"? - Answer ️️ -Magma is formed deep in the Earth and...

Anion - correct answer A negatively charged ion Aphanitic - correct answer An igneous rock texture that refers to the grains not visible to the naked eye, and therefore indicative of fast cooling. Aureole - correct answer The zone of metamorphosed rock surrounding an igneous intrusion and showing the effects of contact metamorphism Bar - correct answer A unit of pressure equal to 10 to the 6th dynes/cm2, approximately one atmosphere (atm) Bowen's Reaction Series - correct a...

Which of the following provide scientists with evidence that Earth's interior has distinct layers? - correct answer Behavior of seismic waves traveling through Earth's interior Which of the following best describes Earth's outer core? - correct answer metallic liquid Which of the following lines of evidence was used by Alfred Wegener to support his theory of continental drift? - correct answer ...

Subduction A geological process in which one edge of a crustal plate is forced downward into the mantle below another plate and melted Asthenosphere The lower part of the mantle Lithosphere The upper part of the mantle and the crust Atmosphere The air and area that is above the crust and below space Core The extremely hot, solid, and dense center of the earth, which is believed to be composed of iron and nickel Mantle Between the core and the crust, liqui...

Most planets (like Earth) are chemically differentiated. This means that nickel and what are concentrated at the core and lighter elements make up the crust? - correct answer iron True or False. Most of the energy sources human society uses are the result of past life-forms that have died, decayed and become part of the Earth's crust. - correct answer True The processes of the rock cycle are typi...

rock Naturally occurring solid mixture of 1 or more minerals and organic matter. rock cycle series of process in which rock forms changes is destroyed and reforms by geological processes erosion process by which wind water ice or gravity transports soil and sediment from one location to another Deposition the process in which eroded material is laid down composition chemical make-up of a rock texture quality of a rock based on the size, shape and position...

asthenosphere - correct answer the soft layer of the mantle that the lithosphere floats on climate system - correct answer all the earth system components that determine climate on a global scale and how climate changes with time core - correct answer the central part of the Earth crust - correct answer ...

Mineral a naturally occuring, inorganic crystalline material with a unique chemical composition. Silicate any one of numerous minerals that have an oxygen and silicon tetrahedron as their structure Brainpower 0:01 / 0:15 Silicon Oxygen Tetrahedron a structure composed of four oxygen atoms surrounding a silicon atom that constitutes the basic building block of silicate minerals Streak the color of a mineral in powder form. Luster the appearance or quality of l...

Cleavage - correct answer The way minerals break along planes Hardness - correct answer The resistance that a surface of a mineral offers to scratching. Hardness depends on the crystal structure Specific Gravity - correct answer The ratio of the weight of any mineral to the weight of an equal volume of water Diaphaneity - correct answer ...
