Continental Drift
Rocks, Rocks, Rocks!!!
How's the WEATHER?
Flashback to 6th/7th Grade
Scary Stuff
100
200-300 million years ago, all of the earth's continents were connected into this one landmass or "supercontinent"
What is Pangaea?
100
Type of rock created by heat and pressure
What are metamorphic rocks?
100
This can happen through acid rain or when a change by acidic nature breaks down a large rock.
What is chemical weathering?
100
The brain of the cell. This contains genetic or hereditary information and controls what the cell does.
What is the nucleus?
100
This type of devastating action occurs at transform plate boundaries because the plates are sliding against each other, creating tension. An example would be the San Andreas Fault in California.
What is an earthquake?
200
This scientist developed the theory of plate tectonics, which states there are small plates beneath the earth's crust that move around, causing continental drift.
Who is Alfred Wegener?
200
Type of rock created by the cementing and compacting of minerals and rock fragments into layers.
What are sedimentary rocks?
200
This can happen tree roots or animal burrows break up a large rock.
What is physical weathering?
200
The "powerhouse" of the cell, the oval-shaped mighty mitochondria, produces this type of energy?
What is ATP
200
This type of devastating act occurs at convergent or divergent plate boundaries. It's especially true of convergent plate boundaries, where the plates collide and create these special types of mountains.
What are volcanoes?
300
These circular motions in the earth's mantle cause heat from the earth's core to rise, then cooler, more dense liquid to sink. It is one of the causes of the plate tectonics theory.
What are convection currents?
300
Type of rock created by the cooling of magma. Often found near volcanoes.
What are igneous rocks?
300
These help keep soil compact and tight, which helps prevent erosion, by holding the soil together.
What are plant roots?
300
This process produces haploid (half) cells because offspring only get half of the genetic information from each parent.
What is meiosis?
300
This hot stuff upwells to create new seafloor at divergent plate boundaries.
What is magma?
400
Large-scale motion of plates beneath the earth's crust that move around and interact with each other at boundaries (convergent, divergent, transform). Can cause mountains, volcanoes, earthquakes, and continent movement.
What is the plate tectonics theory?
400
Shows how different rocks can change into other types of rocks. Often displayed in a diagram showing metamorphic, igneous, and sedimentary rocks turning into each other.
What is the rock cycle?
400
When a force, such as wind or water, carries bits and pieces of rock that have been broken up by weathering to a new location.
What is erosion?
400
These two subatomic particles are almost the same size and mass and are in the atom's nucleus together.
What are protons and neutrons?
400
When magma upwells, it creates new seafloor at mid-ocean ridges. This is where the old crust is recycled to make room for the new crust.
What are ocean trenches?
500
Two pieces of evidence that support continental drift, or the movement of continents.
What are similar fossil records on different continents and the puzzle piece shapes of South America and Africa?
500
If we look at a rock's layer, this would most likely be the oldest layer.
What is the bottom layer?
500
Sometimes, we see giant holes in the middle of giant rocks. This happens when bits and pieces of the rock are weathered and eroded away. This is the forces that causes this.
What is wind or water?
500
This type of reaction creates a new substance, such as when something is set on fire and burned. It CANNOT be reversed to the former substance.
What is a chemical reaction?
500
The inner core of the earth is hotter than the surface of the sun. This is because these three things INCREASE the deper we go into the earth's crust.
What are temperature, pressure, and density?
