The Earth’s structure is made up of six layers. The top layer is the crust. The crust took on a solid form billions of years ago. It is broken up into huge, very thick 'plates'. The plates then rest upon a rocky mantle. Shifting of the plates can cause major alterations to the Earth’s surface by way of events such as earthquakes and tsunamis.
1 .
Which layer of the Earth is the thinnest?
Mantle
Lithosphere
Core
Crust
The top layer is the thinnest. The crust's thickness varies from as little as 2 miles at the mid-ocean bottom to 70 miles under some continental mountain ranges
2 .
The Earth’s crust is made up of two parts that include …
oceanic crust and the continental crust
mountain ranges and valleys
ocean floor and volcanic mountains
water and land
The Earth’s crust consists of oceans and land masses or continents
3 .
Which layer of the Earth creates the Earth’s magnetic field?
Core
Crust
Inner mantle
Outer mantle
Iron has a lot to do with the Earth’s magnetic field. The core is made up of mostly iron
4 .
Which of the following best describes the mantle?
Solid rock
Liquid and solid rock
Solid metal
Liquid and solid metal
The mantle contains rocks and molten lava. It is not solid nor does it contain metal
5 .
A divergent boundary is when …
a plate slips down
two plates collide with each other
two plates move away from each other
a plate pushes upward
Divergent refers to being separate and different. A divergent boundary is where two things separate from each other
6 .
A convergent boundary is when …
a plate slips down
two plates collide with each other
two plates move away from each other
a plate pushes upward
Convergent refers to things moving towards each other rather than away from each other
7 .
The inner core of the Earth is made up of mostly?
Magma
Nickel
Iron
Granite
The core is made up of mostly a hard metal. Magma is liquid, nickel is soft and granite is not a metal
8 .
The Earth’s structure is made up of six layers that include?
Rock, gas, lava, crust, water, land
Inner core, outer core, lower mantle, upper mantle, lithosphere, crust
Crust, mantle, lava, lithosphere, core, rock
Core, inner mantle, outer mantle, lava, rock, crust
Although some say there are only four layers, we have two additional layers that connect other layers. The four main layers are the core, the lower mantle, the upper mantle and the crust. The layer between the upper mantle and the crust is known as the lithosphere. The core also consists of an inner core and an outer core
9 .
The lithosphere layer includes part of …
the ocean and crust
lower and upper mantle
the continental crust
the crust and upper mantle
This layer is just under the surface of the Earth’s crust. Some consider it to be part of the Earth’s crust. It connects the crust with the upper mantle
10 .
What is the thick, hot, rocky layer around the outer core called?
Crust
Mantle
Lithosphere
Magma
Where the core is solid, the area around the core is a mixture of both rock and molten lava. The crust is the Earth’s surface. The lithosphere is just below the Earth’s surface. Magma is not one of the layers. That only leaves the mantle
