EARTH
What is the molten rock that forms new rock and is found deep inside the earth?
magma
What is the main reason for the different layers of the atmosphere and geosphere?
Density
Convection currents occur here?
upper mantle or asthenosphere
This layer is divided into 2 parts based on density. the two parts are oceanic and continental
crust or lithosphere
What is the ability to do work called?
Energy
What blast rocks from deep interior of the earth that provides information about the interior of the earth?
volcanoes
What is a layer of solid rock that includes dry land and ocean floor?
crust
More water is contained here than in all the oceans.
Rocks
What part of earth's layers is pure iron and nickel and is solid?
inner core
This is a remnant of an organism that live and died long ago?
Fossil
This rock is made from broken pieces of other rock that gets layered over time.
sedimentary
What are the three main parts of the earth? remember two of them have 2 parts (inner/outer, and upper/lower)
crust, mantle and core.
These forces come from a subduction zone and shape the land's surface by building up mountains and sometimes lava breaks through them.
volcanoes
What two main sources of energy drives the earth system?
heat from the sun and heat that comes out of earth as it cools
How many layers are there in the earth
5
What main sphere of gas that surrounds the Earth's geosphere system?
atmosphere
Where is new crust being formed?
Mid-ocean ridge
The continental crust is mainly made of of granite which is cooled below ground. This type of rock is called?
Intrusive igneous
Mechanically speaking, what layer has convection currents?
asthenosphere
Which crust subducts under the the other
Oceanic
Mechanically speaking, what is the transitional zone of the asthenosphere to the outer core?
mesosphere
What layer of earth is responsible for the magnetic field that protects us from the sun's radiation?
outer core
How many parts are there to the core and describe their state of matter
outer (liquid)/inner (solid)
What do scientists believe the movement of the earth's outer core causes?
a magnetic field
how does convection work?
Heat rises and cools
