100
These two surface processes work together to break down rocks into sediment and then move them to a new location.
What are weathering & erosion?
100
This sphere includes all of Earth's living organisms.
What is the biosphere?
100
This scientific law states that in undisturbed sedimentary rock layers, the oldest layer is at the bottom.
What is the Law of Superposition?
100
This is the thinnest, outermost layer of the Earth.
What is the crust?
100
Which Florida landform is a tall hill of sand created by the deposition of wind?
What is a dune?
200
This Florida landform is the "mouth" of a river where sediment is deposited, often creating a triangular shape.
What is a delta?
200
While weather describes short-term conditions like a rainstorm today, this term describes the long-term patterns of temperature and precipitation in an area.
What is climate?
200
This term refers to the total collection of all fossils ever found on Earth, which provides evidence of how life forms have changed and evolved over time.
What is the fossil record?
200
This layer of the Earth is the most dense, metallic solid made primarily of iron and nickel.
What is the inner core?
200
While the Inner Core is solid due to intense pressure, this layer of the Earth is the only one that is a liquid, and its movement creates Earth's magnetic field.
What is the outer core?
300
This type of rock is formed deep underground through intense heat and pressure, often near plate boundaries.
What is metamorphic rock?
300
When a plant (biosphere) performs photosynthesis, it pulls & releases gases into this sphere of the Earth.
What is the atmosphere?
300
Unlike relative dating, this process uses the decay of unstable elements to determine the exact age of a rock or fossil in years.
What is absolute dating (radioactive dating)?
300
The movement of Earth's plates is driven by these "loops" of rising and sinking magma within the hot mantle.
What are convection currents?
300
In this layer you would find the oldest fossils based on the image.
What is Layer #1?
400
Commonly found in Florida, this is an underground layer of permeable rock (limestone) or sediment that allows water to flow through it, filters it and stores it for human use.
What is an aquifer?
400
Waves eroding a coastline is an example of these two spheres of the Earth interacting.
What is the geosphere and hydrosphere?
400
If a scientist finds a fossil of a tropical plant in the frozen ground of Antarctica, it provides physical evidence that this must have changed over millions of years.
What is climate (or location of the continent)?
400
This type of plate boundary occurs where two plates slide past each other, often causing rapid changes like earthquakes.
What is a transform boundary?
400
This term refers to the clearing of wide areas of trees, which often leads to increased soil erosion and more carbon dioxide in the atmosphere.
What is deforestation?
500
To transform a Sedimentary rock into an Igneous rock, it must first undergo these two specific processes within the Earth.
What are melting (to magma) and then cooling/hardening?
500
Meteorologists are predicting a two-week-long heatwave with no rain for the entire state of Florida. Even though this covers a longer period of time, it is still this concept.
What is weather?
500
The discovery of identical rock layers and fossils on separate continents, such as South America and Africa, supports the theory that these landmasses were once this.
What is joined together (Pangea/ supercontinent)?
500
Deep-ocean trenches and volcanic mountain ranges are usually formed at this type of boundary, where one plate sinks beneath another.
What is a convergent-boundary (subduction zone)?
500
When humans build large cities with many roads and parking lots, it is called this. It prevents rainwater from soaking into the ground.
What is urbanization?
