science final guide

What are the layers of the earth? Crust, mantle, outer core, inner core.
Describe earths mantle The mantle is made out of rock that is very hot, but solid.
What happens when converging boundaries collide? one of the plates come up.
What are the 3 types of faults? Compare and contrast them Strike-slip, reverse, normal. They all move. They all move in different ways.
Where would you find volcanoes? Along the ring of fire.
What land form would be created by continental plate collision? A mountain range.
What is the convection currents job? To transfer heat within a fluid.
Theory of plate tectonics. Earth's plates are in a slow, constant motion, driven by convection currents in the mantle.
What are the 3 types of plate boundaries and what do they form? Divergent, convergent, transform. Divergent - rift valley Convergent - mountains Transform - a fault
What are the 3 types of rock; where are they found and formed? Sedimentary - found in oceans, rivers, and deserts; formed by weathering, erosion, deposition, and compaction. Metamorphic - found in mountains; A sedimentary or igneous rock heated by the mantle Igneous - found at divergent plate boundaries;
Law of superposition In undisturbed horizontal sedimentary rock layers the oldest layer is at the bottom. Each layer above it is younger.
How do rocks change into each other? They change into each other by weathering and erosion, deposition, heat and pressure, melting and volcanic activity.
What are the erosion processes? running water, wind, ice
What are the weathering processes? Freezing and thawing, plant roots, acid
How are sinkholes and caves formed? Sinkholes - formed by ground water dissolving limestone below the surface. Caves - Water above sinks under ground and dissolves the limestone.
What are types of glaciers? What are other types of land features? Glaciers - continental, valley Land features - mountain, river, valley
What is the difference between show and wild caves? Show caves are public caves where people can go inside, Wild caves are dangerous caves that allow no people inside.
What is the smallest unit of life? A cell
What is the difference between multi cellular and unicellular? Multi cellular - cells carry out life through multiple cells. unicellular - cells carry out life through one cell.
What are the functions of these systems: circulatory, digestive, and nervous? Circulatory - transports oxygen, nutrients, and wastes; fights infection; helps regulate body temperature Digestive - breaks down food; absorbs nutrients; removes food wastes Nervous - controls body's responses to changes inside and outside environments
What are some of the structures and functions of plant and animal cells,. Nucleus - controls the cell Ribosomes - produce proteins Cell membrane - controls which substances pass in and out of the cell.
Differences between plant and animal cells. Animal cells have lysomes, while plant cells have a cell wall and chloroplasts.
Purpose of mitosis. cell regeneration, growth, and asexual reproduction.
How does zygote develop into an embryo It divides many times by mitosis.
First 3 stages of mitosis and what they do. Prophase - chromosomes condense into shpes that can be seen under a microscope. Metaphase - each chromosome attaches to a spindle fiber at its centromere. Anaphase - the cenetromere of each chromosome splits.
last stage and short description of mitosis Telophase - the chromatids move to opposite ends of the cell and two nuclei are formed. Mitosis - The cell's nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell.
what are the functions of the exertory system and the respiratory system. Exertory - removes waste from the body Respiratory - brings in oxygen needed in cells; removes carbon dioxide from the body.
Draw and label parts of the plant and animal cell and compare and contrast them I Drew both cells on the study guide. Animal cells have lysomes, while plant cells have a cell wall and chloroplasts. They both have a nucleus and ribosomes.
