Chemistry
What is the basic unit of matter?
Atom
The nucleus contains ____________ and ___________.
protons, neutrons
The crust and the upper mantle make up the
Lithosphere
What is the most abundant element found on Earth
Carbon
Explain how human activity contributes to excess Carbon in the atmosphere?
Burning fossil fuels and deforestation destroys carbon sinks, releasing more carbon dioxide.
What type of bond shares electrons?
Covalent bonds
The outer core is made entirely of _______ _______
molten metal
Tectonic plates move due to the convection currents in the
Asthenosphere
Provide at least one example of how Nitrogen can be fixed
Bacteria
Lightning
Haber-Bosch process
List the properties of water and the effects that they have
Cohesion
Adhesion
High Specific Heat
Less dense when frozen
Organic compounds always contain which element?
Carbon
The main greenhouse gases include methane and ___________ ___________.
carbon dioxide
Which boundary type creates earthquakes?
Transform
Provide at least one example of carbon sinks
Limestone
Forests
Oceans
Explain the difference between covalent and ionic bonds.
Covalent bonds share electrons, while ionic bonds transfer electrons.
What is a compound made of?
Atoms of two or more of different elements
Eutrophication can cause __________ or low oxygen levels.
hypoxia
The atmosphere contains about 78% of which gas?
Nitrogen
What does the Law of Conservation of Mass state
Matter can be created nor destroyed
Describe the process of the water cycle.
Evaporation, condensation, precipitation, transpiration, runoff
A molecule is created when?
Two or more atoms are joined by covalent bonds.
Bacteria in soy beans and peanuts help to nitrogen.
fix
Which type of feedback loop stabilized a system?
Negative
Explain the process of Eutrophication
Eutrophication can lead to hypoxia or low oxygen conditions when the excess plants die. Bacteria remove oxygen from water when they decompose the dead plants. This leads to fish kills and dead zones.
How do tectonic plate movements influence climate? How did Pangea accelerate or boost evolution?
Plate movements alter and change landforms, which changes in rain and climate patterns. Pangea isolated and brought together many species, causing them to quickly adapt and evolve over time.
