Rocks
A changed rock formed from pressure and heat is a _____________ rock.
Metamorphic rock
Rivers carrying soil and rocks away through a valleys is an example of __________________
erosion (because the soil and rocks are being moved)
Volanoes and Earthquakes are found (near or away) from the plate boundaries between oceans and continents?
Volcanoes and Earthquakes are found near the plate boundaries.
The ice cubes in a freezer are melting. Which change most likely is causing the ice cubes to melt?
An increase in the temperature inside the freezer
What do animals have to do when they require the same food source or habitat?
Animals have to compete.
Ice or wind can break rocks into smaller pieces. What is this process called?
Weathering
What two things increase as you go closer to the Earth's core?
Heat and Pressure
A mixture are a combination of two or more things that can be mixed and separate. A solution is a special mixture where one substance dissolves.
If producers are killed in a food web, how are the consumers affected?
The animals that eat plants would die first, then the carnivores will die next.
What type of rock is formed under intense heat and pressure?
metamorphic
How are weathering and erosion different?
Weathering breaks the rock down, erosion carries or moves the rock pieces
How are the crust and mantel different than the inner/outer core?
The crust and mantel are made up of rocky material and the inner and outer core are made of iron and nickel?
Movement of material within Earth causes large continent-sized plates to move slowly about Earth's surface driven by ___________________ energy.
Thermal
Bears are omnivores that eat berries and meat. What is their niche? (Producer, Consumer, Decomposer)
Consumer
Which type of rock may have fossils and is made of layers of sediments being cemented together?
Sedimentary
What does weathering mean?
to break apart
What three landforms are caused by current and past plate movements on Earth?
Mountains, Trenches, and Mid-Ocean Ridges
Where are the oldest and youngest fossils found in the ground?
The youngest are found at the surface and the oldest are found at the the bottom.
Producers that live in ecosystems near the ocean's surface receive their energy from —
The sun
Describe the rock cycle.
A never-ending cycle of how rocks change. For example, Magma turns to igneous rock. Igneous rock weathers down into sedimentary rock. Sedimentary rock forms into metamorphic rock under heat and pressure.
What does erosion mean? Give an example.
Is it a fast or slow process?
Erosion is when particles are carried or moved away. For example, waves washing away the broken parts of cliffs.
Erosion is a slow process.
Where are most earthquakes and volcanoes found?
How do earthquakes form?
Earthquakes are found near the boundary lines and the form when plates slide past/rub against each other.
Which of the following is the best way to find out what life was like billions of years ago on Earth?
Studying lots of fossils
Jellyfish live near the ocean surface because it provides them with the most access to their food sources, like plankton and small fish, which live where sunlight reaches. Jellyfish largely rely on ocean currents to move, making the surface a good location to float and swim. Select each of the following that are reasons why jellyfish live near the surface of the ocean:
A. to filter nutrients
B. access to food sources
C. to move using ocean currents
D. because they need colder temperatures to survive
B. access to food sources
C. to move using ocean currents
