Question 1

Proxy records

Answer 1

Records or data collected from other sources

Question 2

Geomorphology

Answer 2

The study of origins and evolution of the earth’s landforms, and the factors which affect them.

Question 3

Sedimentary Rock

Answer 3

Rock formed over millions of years due to the accumulation of sediment

Question 4

Igneous Rock

Answer 4

Rock which is formed by the cooling of molten magma

Question 5

Metamorphic Rock

Answer 5

Rock formed from other rocks that have been changed due to heat or pressure

Question 6

Basalt

Answer 6

The most abundant igneous rock found on the planet

Question 7

Unconsolidated

Answer 7

Often loosely formed mass of soil, rock and other parts that is weak and easy to break

Question 8

Lithology

Answer 8

The general physical characteristics of rocks

Question 9

Permeable

Answer 9

Allows liquid to pass through it

Question 10

Impermeable

Answer 10

Will not allow liquid to pass through it

Question 11

Recession Rate

Answer 11

The rate at which the land recedes

Question 12

Temporal

Answer 12

Relating to time

Question 13

Hydraulic Action

Answer 13

Mechanical weathering cause by the force of moving water currents rushing into a crack in the rock face and forcing apart

Question 14

Attrition

Answer 14

The wearing away of material as it collides together continually

Question 15

Corrosion

Answer 15

Erosion caused by the acidity within the water corroding the rock

Question 16

Abrasion

Answer 16

A type of erosion caused by the process of scraping or wearing something away.

Question 17

Sediment Cell

Answer 17

Cells within which the movement of sediment is functionally separated and discrete from the next

Question 18

Dynamic Equilibrium

Answer 18

The state at which inputs into a system equal outputs

Question 19

Succession

Answer 19

The process of change in the species structure of an ecological community over time

Question 20

Longshore drift

Answer 20

The movement of material along a coast by wave action which approach at an angle to the shore but recede directly away from it.

Question 21

Tombolo

Answer 21

A bar of sand or shingle joining an island to the mainland

Question 22

Cuspate forelands

Answer 22

Formed due to longshore currents by the accretion of sediment, they extend outwards from the shoreline in a triangular shape.

Question 23

Rotational Slump

Answer 23

Where the slope fails and slide down due to undercutting or weathering of unconsolidated material

Question 24

Mass Movement

Answer 24

The geomorphic process by which soil, sand and rock move downslope typically as a mass, largely under the force of gravity or erosion

Question 25

Rotational scars

Answer 25

The scar left behind due to rotational slump

Question 26

Talus screes

Answer 26

A mass of small loose stones that form or cover a slope a mountain due to weathering. They typically have a concave upwards form.
