Chapter 1 Flashcards
What is a hypothesis?
A statement of prediction.
What is collecting facts?
Observation
What is a tested and confirmed hypothesis called?
A Theory
What is a paradigm?
A theory that explains a large number of interrelated aspects of the natural world.
What is the study of earth called?
Geology
What is meteorology?
The study of the atmosphere and processes that produce weather.
What is astronomy?
The study of the universe
What is the study of the ocean?
Oceanography
What is the water part of the Earth called?
The hydrosphere
What is the biosphere?
The living part of the Earth
What is the thin, tenuous blanket of air that covers the earth called?
The atmosphere
What is the geosphere?
The solid part of the Earth
What are the compositional layers of earth? Which is the smallest and largest by volume? And which is the densest?
- Crust (smallest volume)
- Mantle (largest volume)
- Core (highest mass/density)
What is the crust?
The rigid outer layer of the Earth
Name the 4 spheres of the earth system.
- Hydrosphere.
- Atmosphere.
- Biosphere.
- Geosphere.
Articulate why the scripture Genesis 1:6-11 was chosen for chapter 1
When “God said, let there be something to divide the water in two.” he made the geosphere rise up to separate the water in the hydrosphere.
What is the mantle?
Molten rock (largest volume)
What is the liquid metal part of the earth (it has the highest mass)?
The core
What layers are based on the materials behavior?
The functional layers
What layers are based on what it’s made of?
The composition layers
What is the lithosphere composed of?
The crust and the upper mantle (protection)
What is the asthenosphere made of?
The lower mantle (coldest magma)
What is the geologic plate?
It’s a piece of lithosphere
What is a system?
Parts that form a complex whole
What is the difference between an open system and it closed system?
In an open system, energy and matter can flow in and out freely, but a closed system is self-contained and matter cannot get out
What are the steps of the scientific method?
- Ask a question.
- Create hypothesis.
- Test hypothesis.
- Collect data.
- Analyze data.
- Publish/share data
What are the compositional layers?
- crust(smallest volume)
-Mantle(largest volume) - core(highest mass/density)
What are the functional layers?
- lithosphere
- asthenosphere
What is the continental crust?
- It is primarily potassium and silicone
- It is light colored
- it has a lower density
- it’s primary rock is granite
Tell me about the oceanic crust.
- it is primarily iron and magnesium
- dark colored
- it has a higher density
- It’s primary rock is basalt
