involves the processes that move weathered material from place to place. It occurs through the forces of gravity, wind, ice, water, and human actions
What is erosion
100
Sedimentary rock is formed when sediments from other rocks settle in water. The sediments form rocks when: a. volcanoes erupt and millions of years have passed. b. cement is added to the layers of sediment through the rock cycle. c. remains of dead plants and animals settle between the layers. d. the layers of sediment undergo great pressure for millions of years.
d. the layers of sediment undergo great pressure for millions of years.

Choose the BEST explanation for how sediments are formed. a. Sediments are formed by rocks baking in the sun over millions of years. b. Sediments are formed by volcanoes erupting and spewing lava into the air. c. Sediments are formed by millions of years of wearing by the wind, rain, waves, moving water, and glacier movement. d. Grinding up used materials and depositing them in rivers and landfills form sediments.
What is Sediments are formed by millions of years of wearing by the wind, rain, waves, moving water, and glacier movement.

Choose the type of rock that is formed when magma cools and becomes a solid. a. sedimentary rock b. limestone c. igneous rock d. mineral
Igneous Rock
300
refers to the slight melting of the bottom surface of the glacier that causes freezing and thawing in the cracks of the rocks below. The loosened rocks become embedded or attached to the ice and move with the glacier.
What is glacial plucking
300
Igneous rock is formed from: a. minerals that seep through sediment and dissolve organic material. b. weathering and erosion of mountains and rock formations. c. deposits from layers of earth materials along streams and rivers. d. molten rock material that cools and hardens to form a solid.
d. molten rock material that cools and hardens to form a solid.
300
Rocks are formed from weathering and erosion of sediments and a combination of great heat, great pressure, and/or great periods of time. There are three basic classifications of rocks that differ due to their formation: sedimentary, metamorphic, and igneous. The difference between the formation of igneous rock and metamorphic rock is: a. heat and different minerals. b. erosion and pressure. c. pressure and hardening. d. time and pressure.
What is d. time and pressure
300
Choose the BEST answer that describes what makes up soil. a. sand, dirt, leaves, and sticks b. worms, roots, moles, and microorganisms c. sediments from rocks, decomposing organic material, and microorganisms d. mud, clay, and sand
c. sediments from rocks, decomposing organic material, and microorganisms
300
What sedimentary rock has once living organisms in it?
What is limestone.
400
is a solid element or compound with a unique structure of atoms and are formed by natural processes and are the building blocks of rocks.
What is Minerals
400
What is the BEST explanation for different colored specks and different markings in some rocks? a. Rocks reflect colors from the Earth. b. Rocks are a mixture of minerals. c. Rocks are fossils that give evidence of ancient life. d. Rocks have been colored and carved by chemicals and sunlight.
What is B. Rocks are a mixture of minerals.

What is the difference between intrusive and extrusive igneous rocks.
Intrusive: Rocks formed from inside the volcano (magma) that cools slowly. Extrusive: Rocks formed from lava (outside the volcano) cooling quickly.
