Evidence for impact craters:
Distinctive craters which can be seen on the surface of the Moon.
Craters have a depression with a of broken rock.
Earth's surface does not show craters.
In there is a 50000 year old meteor crater.

Explanation

Question 14 of 30

2

Why are meteorite craters less extensive on Earth than on the Moon?

Select one of the following:

The Earth's crust is subject to weathering, erosion and recycling at plate margins all of which destroys craters.
The Earth's crust is subject to weathering, erosion which destroys craters.
The Earth's crust is stronger.

Explanation

Question 15 of 30

2

Select from the dropdown lists to complete the text.

The impact of a meteor causes:
- Material to be ( ejected, destroyed ) and ( quartz, muscovite ) grains to be violently shocked.
- Rock ( strata, beds, sequences ) to be tilted.
- Material at depth to be ( brecciated, destroyed, broken up ).
- Ejected material falls back to the surface resulting in an ( inverted, reversed ) sequence of rock.
This is because material closer to the surface is ejected ( first, last ) and falls back to the surface ( earlier, later ).

Explanation

What is radiometric dating?

Select one of the following:

A method used to date rocks which uses the decay of radioactive isotopes.
A method used to date meteorites which uses the content of radioactive elements.

Explanation

Question 18 of 30

2

Radiometric dates are given with tolerances to express a degree of uncertainty.

Select one of the following:

True
False

Explanation

Question 19 of 30

2

Radiometric dating can be used to determine the ❌ of an object.
2 values are needed:
- The ❌ at which the isotope decays, (the ❌)
- The amount of radioactive ❌ that was incorporated into the object when it formed.

Radiometric dates are given with ❌ to express a degree of ❌ as the process is complex.

Select from the dropdown lists to complete the text.

Stony meteorites are thought to represent the ( mantle, core, crust ) because they contain the same minerals that are found in the Earth's mantle.
Metallic meteorites are thought to represent the ( core, mantle, crust ) as they are made of the same elements as the Earth's core.
Carbonaceous chondrites are thought to represent the ( sun, moon, Earth ) because they have similar composition however they have ( fewer, more ) volatiles.
