ROCK CYCLE
Which rock type is a result of the rapid cooling of magma?
IGNEOUS
What is a convergent plate?
Plate boundary where 2 plates move forward each other. The one that sinks sub ducts and melts.
What is the difference between magma and lava?
Magma is composed of molten rock and is stored in the Earth's crust. Lava is magma that reaches the surface of our planet through a volcano vent.
THREE types of soil?
Clay, Silt, Sand
Continental and oceanic
What is the difference between weathering and erosion?
Weathering creates sediment, while erosion is the process of transporting sediment.
Wegener stated that Pangaea began to break apart about 200 million years ago? Why did people laugh at this idea?
Wegener could not explain what made the continents move.
Where would you find the most volcanoes in the world at? Where is it located?
The Ring of Fire; Pacific
What is loam and what is it best suited for?
A mixture of all 3 types of soil and its best suited for plant life.
Mountains are caused by what?
A sedimentary rock is buried deep within the earth. At a certain depth, the rock melts completely and recrystallizes. What BEST identifies what type of rock is formed post re crystallization?
IGNEOUS rock
What is focus?
The point inside the Earth where an earthquake starts.
Both the Hawaiian and the Galapagos Islands are formed from what type of volcanoes?
Hot Spot
What does it mean when soil is impermeable?
does not allow water to pass through it.
What is an mid-ocean ridge? How does it form?
A mid-ocean ridge is an underwater mountain range. ; uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary
In the desert, a rock can experience seasonal cycles of freezing and cooling. The heat of the day causes ice to melt and the cold temperatures at night causes water to freeze and expand inside cracks present in the rock. What type of weathering is this?
Physical
Where will earthquakes mostly likely occur at?
Where Earth's tectonic plates are moving together
What is the largest type of volcano?
Shield
The decayed remains of animal and plant life in soil are known as?
Humus
What is the first step in the formation of sedimentary rock?
Erosion!
What do wind and water do to rocks at the surface? What is this called?
It becauses smooth and this process is called abrasion
A geologist is measuring the magnitude of the last big earthquake that struck South America. She is able to calculate the magnitude because earthquakes release energy that create what? (HINT: earthquakes create vibrations)
Seismic waves
Volcanic mountains tend to form on?
Divergent
What are the 4 layers of soil? (HINT: the 3rd layer is called parent ;3)
Top Soil, Sub Soil, Parent, and unweathered
(FOR BOTH TEAM FIRST TO SAY THE ANSWER GETS THE POINT) When the Mid-Altantic Ridge (mountains) was formed, where was the youngest rocks located?
Close to the top on both sides of the mountains
