A scientist who studies the Earth (and rocks)
What is a geologist.
100
I was formed by tiny pieces of rock and sand. You can see my layers.
What is a sedimentary rock?
100
I am formed from bits and pieces of recycled rocks and minerals.
What are sedimentary rocks?
100
The moving of sand from the top of the mountain to the beach.
What is erosion?
100
The water rose and destroyed people's houses. When the water slowed, new sand and sediments were deposited.
What is a flood?
200
Geologists begin their work outdoors.
What is fieldwork?
200
I was once a sedimentary rock until heat and pressure changed me into this.
What is a metamorphic rock?
200
Water freezes in the cracks of rocks. Water expands when it freezes, breaking the rocks apart.
What is weathering?
200
Small pieces of rock and sand settling at the bottom of the ocean (or just on our beaches).
What is deposition?
200
A huge blast of hot gases, ash, and pumice was let loose from a mountain top.
What is a volcanic eruption?
300
Geologists use this scale to test for hardness.
What is the Mohs Hardness Scale?
300
I was once molten rock in the magma chamber of a volcano until I cooled off and hardened.
What is an igneous rock?
300
A rock buried deep in Earth's crust under much heat and pressure.
What is a metamorphic rock?
300
I slowly rub away all the rough edges of a rock and make it completely smooth.
What is water?
300
The crack along the fault shook for 15 seconds. Major freeways fell. Buildings collapsed.
What is an earthquake?
400
Geologists make note of these properties.
What is color, luster, streak, and hardness?
400
I am an acid and can help geologists determine if there is Calcite present in a rock.
What is vinegar?
400
Volcanoes and earthquakes can often bring molten rock to the surface. Then it cools and hardens into this kind of rock.
What is an igneous rock?
400
I am a frozen river of ice. I erode V-shaped valleys into U-shaped valleys.
What is a glacier.
400
Large amounts of soil slide downhill.
What is a landslide?
500
My color is yellow. I have a hardness of 2.5 to 3. I have a golden yellow streak and a metallic luster.(P 218)
What is gold?
500
I am the remains of dead plants and animals found mostly in sedimentary rocks.
What are fossils?
500
Fossils are usually found here.
What is in sedimentary rocks?
500
Rubbing one rock against another to make smaller rocks and dust.
What is abrasion?
500
A mass of granite broke loose from a cliff. Hundreds of trees were knocked over. It hit the ground at 400 KPH.
What is a rockfall?
