Earth's Materials
Earths three main layers
What are core, mantle, and crust?
The large land mass that all continents were once apart of
What is Pangaea?
Earths four major systems
What are atmosphere, geosphere, hydrosphere, and biosphere?
Provide clues to the age of rocks and how life forms change over time
What are fossils?
The wearing down of Earth's surface structures, loosening and breaking of surfaces such as rocks and minerals
What is weathering?
1
What is crust?
Forms in areas where magma bursts through thin and weak areas of Earth's surface
What are volcanoes?
Includes all living things on Earth
What is biosphere?
The time period where the first land plants, reptiles, fish, spiders, and insects appear
What is Paleozoic?
The average weather in a region over many years
What is climate?
2
What is mantle?
Caused by massive collisions of continental plates
What are earthquakes and tsunamis?
The water in and on Earth
What is hydrosphere?
The time period where movement of the seven crustal plates create mountains and increase earthquakes and volcanoes
What is Cenozoic?
The condition of the atmosphere at a given time
What is weather?
3
What is core?
Form along plate boundaries due to great amounts of energy released in those areas
What are mountain ranges, earthquakes, and volcanoes?
The solid parts of Earth
What is Geosphere?
The time period where the first mammals, frogs, flowering plants, and dinosaurs appear
What is Mesozoic?
The process that removes the rock and minerals broken down by weathering to a new location
What is erosion?
Created by Earth's molten metal core
What is Earth's magnetic field?
Moves continental plates as a result of the rise and decent of magma
What are convection currents?
The gases that surround the Earth
What is atmosphere?
The time period that represents about 90% of geologic time.
What is Precambrian?
Created by upward and downward air movements
What is thunderstorm?
