Vocabulary
#1 What is a natural, non-living solid crystal that makes up rocks called? mineral
#2 What is a part of a mineral formed by a repeating 3-dimensional pattern called? crystals
#3 What do you call the color of the powder that a mineral leaves when it is scratched across a special plate, which can be a different color than the mineral itself? streak
#4 What is water from precipitation that soaks into the ground called? groundwater
#5 What is the laying down of pieces of rock called? deposition
Minerals & Rocks
#1 Minerals with larger crystals have cooled how? very slowly
#2 Minerals with smaller crystals have cooled how? very quickly
#3 These are rocks that have changed as a result of heat and pressure. metamorphic rocks
#4 These are rocks that form when layers of sediment settle on top of one another and harden. They are made of small grains, soil, shells, bits of rock, and dead plant/animal matter. sedimentary rocks
#5 These are rocks that form from the molten rock of volcanoes. igneous rocks
Water Cycle
#1 What is it called when energy from the sun heats liquid water on Earth's surface and changes it into water vapor? evaporation
#2 What is it called when water vapor cools and changes into droplets of liquid water, then gather with ice crystals in the air forming clouds? condensation
#3 What is rain, hail, snow, and sleet known as? precipitation
#4 What is water that falls on land and either runs off and collects in bodies of water or soaks into the ground called? storage
#5 What is the correct sequence of the water cycle? evaporation, condensation, precipitation, storage
Changes to Earth's Surface
#1 Name some slow changes that occur on Earth's surface. weathering, erosion, deposition, moving water
#2 What is eroison? A process of carrying away weathered bits of rock
#3 Sand dunes and river deltas can be formed from deposition. Specifically how are sand dunes and river deltas formed? sand dunes = wind river deltas = water
#4 Name some rapid changes that occur on Earth's surface? earthquakes, volcanoes, landslides
#5 What is it called when a break or crack in rocks cause the Earth's crust to move suddenly? earthquakes
Miscellaneous
#1 What is the source of energy that causes most of the water cycle, and what would happen if the source would stop? Sunlight is the source, and if it stops shining, then the water cycle would stop.
#2 What is the process of rocks in Earth's crust slowing being broken into smaller pieces called? weathering
#3 When water freezes and rocks split apart, what is this known as? physical weathering
#4 Where do earthquakes occur? along a fault line
#5 What is the way the surface of a mineral reflects light called? luster
