fossil – the remains or impression of an organism preserved in rock

• rock layer – a horizontal layer of rock, especially one of several parallel layers arranged one on top of another

• strata – a layer of rock or soil in the ground

• igneous rock – rock formed from cooled, solidified lava/magma

• metamorphic rock – rock that has been changed by extreme heat and pressure

• sedimentary rock – rock formed through the deposition and solidification of sediment that frequently contains fossils

• magma – the molten rock material that originates under the Earth's crust and forms igneous rock when it has cooled—when reaches the surface of our planet through a volcano vent it is also known as lava

• rock cycle – a representation of the transitions made over time amongst the three main rock types

• Law of Superposition – in undisturbed rock layers, the youngest layer is on the top and the oldest layer is on the bottom

• relative dating – to find out the relative order of past events without finding out the exact date of when the events happened

• fault – a break in the Earth’s crust that causes one or both sides to move past each other

• intrusion – when magma comes up into rocks but does not break the surface

• extrusion – when magma comes up into rocks and breaks the surface

• index fossil – fossils that are used to define and identify geologic periods

• fossil record – the information that has been collected from the total number of fossils that have been discovered

• Precambrian time – The earliest part of Earth’s history; the earliest eon. The emergence of multicellular life is generally considered to mark the end of this time period.

• Paleozoic Era – The era following the Precambrian time. The beginning of this era is characterized by a great diversity of marine invertebrate animals. Primitive fish and reptiles, land plants, and insects also first appeared during this time.

• Mesozoic Era – This era followed the Paleozoic Era and included the Triassic, Jurassic, and Cretaceous Periods. It is characterized by the development of flying reptiles, birds, and flowering plants as well as the appearance and extinction of dinosaurs.

• Cenozoic Era – The most recent era of geologic time, beginning from about 65 million years ago to the present. This era is characterized by the formation of modern continents and the diversification of mammals and plants.

• Pangaea – a supercontinent that existed during the late Paleozoic and early Mesozoic eras

• Theory of Continental Drift – this theory states that continents move across the Earth’s surface

• crust – the outermost layer of Earth

• mantle – the middle layer of the Earth that can be found between the core and the crust—this layer is composed of magma

• core – the central or innermost layer of the Earth—it has two distinct layers known as the inner core and outer core

• convection – when heated molecules move from one place to another in a fluid and cause movement—this occurs in the Earth’s mantle and causes movement in tectonic plates

• Theory of Plate Tectonics – this theory states that the Earth’s surface (crust) is divided into plates which move across the Earth’s mantle—the movement of these plates can cause mountain formation and some natural disasters

• plate boundary – the location where two tectonic plates meet

• convergent boundary – a place where two tectonic plates move toward each other and collide

• divergent boundary – a place where two tectonic plates move away from each other

• transform boundary – a place where two tectonic plates slide sideways past each other

1) Mind Movie - after reading the problem carefully, I will ask myself: what scientific facts are important to this story? (jot/underline important information!)

2) Unpacking the Question - after reading the question carefully, I will ask myself: what scientific facts is this question asking me to think about? (keep jotting/underlining if it helps!)

3) Text Features - now that I've read the problem and the question, I will go back to the text features in the story and think: what scientific evidence is going to help me answer the question?

4) Double-Check: Before the timer goes off, I will ask: did I read every word and follow every direction?

Earth’s crust is made up of several types of rock that slowly and continually change over time. The rock cycle can be analyzed to determine the type of rock based on the processes that occurred to form or change it. 

Key Vocabulary

• igneous rock
• metamorphic rock
• sedimentary rock
• magma
• rock cycle

• The Law of Superposition states that horizontal sedimentary rock layers include the oldest layer at the bottom and each higher layer is younger than the layers below it. 
• Geologists can estimate a geological timeline by determining the relative age of rock layers by studying their order, in addition to any disruptions like faults, intrusions, or extrusions of igneous rocks.

• The fossil record can be used to determine the relative age of rock formations and how lands may have been connected in the past. 
• Index fossils are widely distributed and represent a type of organism that existed only briefly (usually found in one rock layer) and can be used to match and date rock layers from different parts of the world.

Paleozoic Era? Mesozoic Era? Cenozoic Era?]]> 2022-03-02 20:17:21 UTC https://padlet.com/josephkind1/ntcxyx0m65enph3g/wish/2074357815 josephkind1 https://padlet.com/josephkind1/ntcxyx0m65enph3g/wish/2135346512 Key Takeaways:

• The Theory of Continental Drift states that all continents were once joined together in a single landmass (known as Pangaea) and have since very slowly drifted apart. 
• Note: Alfred Wegener supported this hypothesis with evidence from land features, fossils, and climates, but his ideas were rejected by the scientific community because he could not explain how the continents moved apart.
