What the difference between erosion and weathering?
Weathering breaks down rocks into smaller pieces in place, which erosion moves these broken pieces away.
What are the three main states of matter
Solid, liquid, and gas
Which of the following is an example of a chemical change?
Burning wood
What is the process by which plants make their own food?
photosynthesis
Components are connected across multiple paths, providing alternative routes for current flow.
Parallel Circuit
How does water cause erosion?
through both raindrop impact and flowing water, which dislodge and transport soil and rock particles
What is an example of a physical change?
Melting ice, ripping paper, or cutting a piece of wood
What is the name of the change that results in a new substance being formed?
Chemical change
Which of the following is an example of a decomposer?
bacteria, fungi, and earthworms
Conductors that allow current to flow between components
Wires
How does wind cause erosion?
strong winds that detach and transport soil particles, eventually depositing them in new locations
What is an example of a chemical change?
Burning wood, rusting metal, or baking a cake
What is an indicator that a chemical change is taking place?
A change in temperature
What is the main role of a consumer in an ecosystem?
to obtain energy by consuming other organisms
The electrical potential difference that drives current, measure
Volts
How are weathering, erosion, and deposition related
closely related geological processes that work together to shape the Earth's surface
What is the difference between a conductor and an insulator?
A conductor allows electricity to flow easily, while an insulator does not.
Which of the following is an example of a chemical change?
Rusting a nail
Which of the following is an example of an adaptation that helps an animal survive?
A giraffe's long neck
What is an electric circuit, and how does it work?
a closed loop that electricity, data, or a signal can flow through
What are the four main ways weathering can happen?
mechanical (physical) weathering, chemical weathering, biological weathering, and mechanical weathering
What is the name of the force that attracts objects with opposite poles in a magnet?
Magnetic force.
What is the main difference between a chemical change and a physical change?
A chemical change involves the formation of a new substance, while a physical change does not.
What is the name for the process by which animals take in oxygen and release carbon dioxide?
cellular respiration
