Unit 1

What is the relationship between a continent and the Earth's plates

A continent is physically part of a plate

Ocean ridges are formed from vertical uplift caused by what type of plate boundary

Divergent

What type of boundary can be described as two giant conveyor belts, facing each other but slowly moving in opposite directions as they move newly formed oceanic crust away from the ridge crest?

Divergent

In this diagram, where the continental crust and oceanic crust meet, what would you expect to occur

Earthquakes

How does the movement of lithospheric plates impact the Earth's surface

Geological events like earthquakes and volcanic eruptions are caused by these plate motions

How can the inner core of the Earth be described?

It is so hot that the elements vibrate in place

According to Dr. Paul Narguizian, professor of Biology and Science Education at California State University, "_____ are generalizations about phenomena while _____ are explanations of phenomena."

Laws, theories

What is an example of a geologic feature found at a divergent plate boundary?

Mid-ocean ridges

Lucia measured the temperature of the water in a pond while making notes about the growth of algae each day. What part of the scientific method is Lucia conducting with these actions?

Observation

Scientists have determined that the size of the earth changes very little. What evidence BEST supports the theory that the earth has stayed relatively the same size through its history?

Ocean crust subducts other pieces of the earth's crust at convergent boundaries

Based on the properties of density and the earth's crust, what is the BEST prediction of the movement of oceanic and crustal plates?

Oceanic plates contain basaltic rock and will sink under crustal plates

What is the relationship between plate tectonics and seafloor spreading?

The movement of plates in Earth's crust is the cause of sea floor spreading

Greta is making a diagram of Earth's layers. How should the temperature be labels on the different layers?

The outer core would be hotter than the mantle

How can oceanic plates be described

They are heavier than continental plates

Why is it beneficial for scientist to share their conclusions with others in the field

To build the body of scientific knowledge
