A group of many mountains that form in the same area.
What is A MOUNTAIN RANGE
100
The Theory that says Earth began as one supercontinent.
What is THEORY OF PANGEA
200
The part of the Earth's inside that is divided into two parts, one solid and one liquid.
What is THE CORE
200
The machine scientists use to record the intensity of an earthquake?
What is A SEISMOGRAPH
200
Two of the 5 minerals that form the majority of rocks?
What is Calcite, Feldspar, Hornblende, Mica, Quartz
200
The term for layers of sediment stacked, like that which a fossil could be found in.
What is STRATA
200
The two types of Plates
What are OCEANIC PLATES, and CONTINENTAL PLATES
300
These two parts of Earth's insides make up the Lithosphere!
What is THE CRUST and THE UPPER MANTLE
300
Two types of seismic waves created by an earthquake.
What is P-WAVES (primary) and S-WAVES (secondary)
300
THREE of the properties we use to describe rocks?
What are Colour, Lustre, Streak, Fracture and Cleavage, Transparency, Hardness.
300
Why are fossils important to us?
What is A WAY TO UNDERSTAND THE PAST, BEFORE WE HAVE WRITTEN RECORDS.
300
Two reasons that Plates are moving. Briefly describe them!
What is Convection currents Subduction Zones
400
What are all the layers of the Earth, and are they solid or liquid?
SOLID Inner core, LIQUID Outer Core, Mantle (Half - Liquid, Half- Solid). SOLID Crust.
400
The difference between Lava and Magma in a volcano is?
What is Magma is molten rock stored in the Earth's crust Lava is magma that reaches the surface of our Earth.
400
The three classes of rocks.
What are IGNEOUS, SEDIMENTARY, METAMORPHIC
400
How is a Fossil formed? ALL STEPS!!
1.Organism Dies and is covered by sediment 2.More sediment piles on and pressures the layer with bone. Hardens into rock. 3. The bone dissolves and leaves a mould. 4. The mould fills with water and minerals crystallize. Forms fossil.
400
Three ways scientists can detect plate movements? Describe each.
What is SONAR MAGNETOMETER SATELLITES
500
How can we tell that the Outer Core is Liquid?
Seismic waves are REFRACTED by this layer.
500
What are 3 types of weathering? MUST GET ALL 3!!!!
What is MECHANICAL WEATHERING CHEMICAL WEATHERING BIOLOGICAL WEATHERING
500
The FOUR tools Scientists use to classify rocks.
What are REMOTE SENSING, GEOPHYSICAL PROSPECTING, GEOCHEMICAL PROSPECTING, EXPLORATION
500
What are the two types of folds that mountains form on? AND which way are they folding.
What is ANTICLINE (up) and SYNCLINE (down)
500
Three forms of evidence for the "Supercontinent" Theory. AND One example for each.
What is BIOLOGICAL - Fossils CLIMATE - Coal and Glacial Scrapings ROCK - Same rock found in mountains.
