The Earth Review
Rock Cycle, Types of Rocks, Classification, Plates, Layers of the Earth, Volcano
| Clue | Answer |
|---|---|
| This proccess breaks rocks down by either chemical or mechanicalchange. What is this called? | Weathering |
| When descrbing what a rock is made of you would use what adjective? | Composition |
| Scientists use composition, grain size and textural features, color, and the presence of fossils for what? | Rock Identification |
| These tools can be used to help a scientist tell what type of rock the are observing? | Classification Key |
| A process when rocks move and cahnge over time due to heat and pressure within the Earth and due to weathering, erosion, and deposition at the surface. These processes and others constantly change rock from one type to another. Name the process. | Rock Cycle |
| Rocks that are composed of layers of sediment cemented together are called what? | Sedimentary Rocks |
| Rocks that are composed of melted and cooled rock such as lava are called what? | Igneous |
| Rocks that are created by heat and pressure are called what? | Metamorphic |
| How old is the earth according to scientists? | Approximately 4.6 Billion years old |
| These clues can provide information about life and conditions of the past. What are they called? | Fossils |
| How many layers are there to the earth? | Four |
| This layer is made of molten metal. What is it called? | Outer Core |
| This layer or the earth is made of solid metal. What is it calleed? | Inner Core |
| When an Igenous or Metamorphic rock becomes weathered it eventually will turn into what type of rock? | Sedimentary |
| When you add heat and pressure to a Sedimentary or Igenous rock what type of rock will it become? | Metamophic |
| When Metamorphic rock is melted by heat and pressure it turns into what type of liquid rock? | Magma |
| When Magma cools it turns into what type of rock? | Igneous |
| When combined these two layers make up most of the earth. What are the names of these two layers? | Inner Core and Outercore |
| This layer of the earth is made of molten rock. What is the name of the layer? | Mantle |
| This is the thinnest layer of the earth. What is the name of this layer? | Crust |
| A person who study's bones is called what? | Palenotologist |
| The movement of rock particles by the action of wind, rain, gravity, and other foces of nature is known as what? | Erosion |
| These types of rocks are created from weathered Igneous or Metamorphic rocks. What is this rock called? | Sedimentary |
| These rocks are created from heat and pressure. What type of rock is this? | Metamorphic |
| This substance is melted rock. What do we call this substance? | Magma |
| This type of rock is created from Magma. What is the name of this rock? | Igneous |
| Rock color, rock texture, grain arrangement, grain size, and grain shape are all used by scientists to do what with rocks? | Classify |
| What type of key can you use to classify rocks by their observable differences? | Dichotomus |
| This type of plate boundary has plates that move apart, and new crust is formed by magama pushing up from the mantle. What is the name of this type of boundary? | Divergent |
| This type of boundary occurs when plates move towards each other, sometimes forcing one plate to slide under the other plate and at other times pushing both plates up. What is the name of this boundary? | Convergent |
| This type of plate occurs when two plates slide against each other in opposite directions. This movement can cause earthquakes. What type of boundary is this? | Sliding or Transform |
| These are vents in the surface of the Earth through which magma, gases, and ash erupt. What are these called? | Volcanos |
| Shaking, rolling, or sudden shock of the Eath's surface caused by the movement of the Earth's plates is called what? | Earthquake |
| The earth's plates are moved by what type of energy? | Thermal |
| Most earthquakes and volcanos are located where? | Plate Boundaries or Faults |
| Trenches and mid-ocean ridges and mountains are caused by what? | Current and past plate movement |
| When materials such as sediments are deposited in a new place what is this process called? | Deposition |
