What is the density of water?
What is the density of water?
1 g/mL
A scientist is doing an experiment where they want to know how much fertilizer would be best for sunflowers to grow the tallest. Would would the independent variable be in this experiment?

Amount of fertilizer
What is convection and why does it happen?
What is convection and why does it happen?
Hot material rises and cool material falls, making a current. This happens because hot material is less dense so it rises and cool material is more dense so it falls
Why does Pangaea no longer exist?
Why does Pangaea no longer exist?
Continental drift occurred, which was caused by plate movement
EXPLAIN why the earth has layers
EXPLAIN why the earth has layers
Planetary differentiation states that each layer has a different density. the more dense materials sunk to the center and least dense materials stayed towards the top
What is a convergent plate bounary?
What is a convergent plate bounary?
Two plates move together
How are mountains formed?
How are mountains formed?
2 continental plates converge and collide, pushing the crust upward
How does folding occur?
How does folding occur?
2 continental plates converge and cause rock to bend and fold on top of each other
Explain how a trench is formed
Explain how a trench is formed
1 oceanci and 1 continental plate converge. Subduction occurs when the oceanic plate slips under the continental plate. the crack formed between the plates is called a trench
Explain how an island arc is made
Explain how an island arc is made
2 oceanic plates converge, subudction occurs. magma rises through the crack that formed. magma cools and stack on top of each other to form a chain of volcanoes
What is a divergent boundary?
What is a divergent boundary?
Two plates separate
What is a rift valley and how is it made?
What is a rift valley and how is it made?
A large crack in the ground formed by 2 continental plates diverging
What TWO things are created by the process of seafloor spreading?
What TWO things are created by the process of seafloor spreading?
Mid ocean ridges and new ocean crust
Name 2 pieces of evidence that proves that seafloor spreading is really happening
Name 2 pieces of evidence that proves that seafloor spreading is really happening
1. the crust is newest by the mid ocean ridge and oldest by the trench 2. there is a pattern of magnetized stripes on the ocean floor
Explain the entire process of seafloor spreading
Explain the entire process of seafloor spreading
1. 2 oceanic plates diverge and form a crack in the ocean floor. 2. magma rises through the crack. 3. magma cools to make new ocean crust and other magma cools and stacks on top of each other to make mid ocean ridges along the sides of the crack. 3. old crust is pushed away 4. old crust is subducted into a trench and gets melted back into magma
What is a transform boundary?
What is a transform boundary?
Two plates strike and slip
What are the three types of seismic waves called?
What are the three types of seismic waves called?
p-waves, s-waves, surface waves
How do earthquakes form?
How do earthquakes form?
2 plates strike and slip past each other. energy builds between the plates and is eventually released in the form of seismic waves
5 earthquakes occur. Here are their magnitudes:
Pacific Ocean = 8.7
Alaska= 5.4
San Fran= 9.1
Indian Ocean = 3.2
Japan= 7.6
Which one of these earthquakes will most likely cause a tsunami?

Pacific Ocean
Explain each step as to how a tsunami is created
Explain each step as to how a tsunami is created
2 oceanic plates strike and slip. Energy builds between the plates and creates an earthquake with a large magnitude. The earthquake makes a large wave form
What are the types of plates called?
What are the types of plates called?
Oceanic and continental
Identify which plate boundary makes each type of fault
Identify which plate boundary makes each type of fault
Normal = diverge, reverse = converge, strike slip = transform
How are hot springs created?
How are hot springs created?
A pool of groundwater is heated up by a hotspot or some other sort of volcanic activity
What type of plate boundary exists between the South American and African plate?
What type of plate boundary exists between the South American and African plate?
Divergent
Explain how a hot spot can create a volcano
Explain how a hot spot can create a volcano
1. hot spot forms when a pool of magma rises close the the surface of earth. 2. plate moves over the hot spot. 3. hot spot burns a hole through the plate magma rises, cools, and stacks to make a volcanic island. 4. the plate moves away from the hot spot and the process starts all over
Explain the 2 major differences between how a hot spot makes a volcano and how island arcs are made
Explain the 2 major differences between how a hot spot makes a volcano and how island arcs are made
1. hot spots make one volcano at a time, with island arcs many are made at once. 2. hot spots are not at a plate boundary, island arcs are at convergent
