Rocks
What is the difference between the formation and characteristics of intrusive igneous rock and extrusive igneous rock?
Intrusive igneous rock is rock that comes from magma cooling inside Earth's crust.
Extructive igneous rock comes from lava cooling above ground.
Define frequency.
Frequency is the number of waves that pass a given point in a given amount of time, usually one second. The faster the frequency, the higher the total amount of energy of the wave.
Your body uses the process called _________ to make new, identical cells to replace those that are lost or damaged.
mitosis
What is geologic time, and what does it have to do with rocks?
Geologic time is a way to measure the sequence of significant events on earth over time. It helps us see change in the rocks and rock cycle.
How do we use electromagnetic energy?
For electricity and other things.
Describe the four steps of mitosis:
Prophase:
Metaphase:
Anaphase:
Telophase:
Prophase: Prophase: the first stage of mitosis, when the nuclear envelope breaks down and strands of chromatin form into chromosomes
Metaphase: Metaphase: the second stage in mitosis, when the duplicated chromosomes attach to the spindle fibers and line up along the center of the cell
Anaphase: the third stage in mitosis, when the duplicated chromosomes move away from each other to opposite ends of the cell
Telophase: the final stage of mitosis, when the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes, creating two new daughter cells
How does the rock cycle transform rocks from one type to another?
By heat, pressure, weathering, erosion, deposition, melting, cooling, compacting, cementing, uplift, and exposure.
What do you get when you combine all the colors of light?
Sun light or white light
What happens during cytokinesis?
Cytokinesis is the division of the cytoplasm at the end of mitosis.
For each key characteristic, list whether it is found in sedimentary, igneous, or metamorphic rock:
Fossils: Crystals: Gas bubbles: Glassy surface: Foliation: Sand or pebbles:
Fossils: sedimentary rock.
Crystals: corse and long crystals are found in igneous rock. Flattened crystals are found in metamorphic rock.
Gas bubbles: igneous rock.
Glassy surface: igneous rock.
Foliation: sedimentary and metamorphic rock.
Sand or pebbles: sedimentary rock.
Name the only part of the electromagnetic spectrum that humans can see with the naked eye.
Optical window
Describe each step of meiosis:
Meiosis I:
Meiosis II:
Meiosis I: where the parent cells produce 2 daughter cells
Meiosis II: Where the 2 daughter cells produce 2 more daughter cells each
What are the types of rocks
sedimentary, metamorphic, igneous
What is the electromagnetic spectrum.
all the knowm wavelengths and frequencies
Meiosis
is a cell containing two complete sets of chromosomes, one from each parent.
