Unit test review 3

1. When was the Solar system formed?

• 100 billion years ago

• 4.5 billion year ago

• 5 billion years ago

• 2 million years ago

Outer core is

• The inner core is a solid sphere composed mainly of iron and nickel at the center of the Earth

• The crust is the outermost layer of the Earth, consisting of solid rock divided into continental and oceanic crust

• The outer core is a liquid layer also made of iron and nickel

• The mantle is a semi-solid layer between the crust and the outer core, primarily composed of silicate rocks

1. Inner core is

• is a solid sphere composed mainly of iron and nickel at the center of the Earth

• core is a liquid layer also made of iron and nickel, surrounding the inner core

• is a semi-solid layer between the crust and the outer core, primarily composed of silicate rocks

• is the outermost layer of the Earth, consisting of solid rock divided into continental and oceanic crust

1. Mantle is

• is a liquid layer also made of iron and nickel, surrounding the inner core and generating the Earth's magnetic field through convection currents. 

• is a semi-solid layer between the crust and the outer core, primarily composed of silicate rocks, and it plays a crucial role in Earth's tectonic activity.

• is the outermost layer of the Earth, consisting of solid rock divided into continental and oceanic crust

• is a solid sphere composed mainly of iron and nickel at the center of the Earth

The Crust is

•  is the outermost layer of the Earth, consisting of solid rock divided into continental and oceanic crust

• is a semi-solid layer between the crust and the outer core, primarily composed of silicate rocks

•  is a liquid layer also made of iron and nickel, surrounding the inner core and generating the Earth's magnetic field through convection currents. 

•  is a solid sphere composed mainly of iron and nickel at the center of the Earth

When Pangea first broke up, what 2 land masses were formed?

• Antarctica and the North Pole

• Europe and Asia

• North and South America

• Gondwana and Laurasia

Where oceanic crust is cracked and magma is emerging, we find

• Archipelagos

• Trenches

• 1. Midocean ridges

• Atolls

What is Continental shelf

• is a gentle slope that connects the continental slope to the abyssal plain, formed by accumulated sediments transported from the continental shelf and slope.

  
  

• is a steep incline that marks the boundary between the continental shelf and the deep ocean floor, descending to greater depths.

•  is the gently sloping submerged portion of a continent extending from the shoreline to the continental slope, characterized by relatively shallow depths and rich marine life.
