Ice  tongue  is  a  glacial  formation  created  by  an  ice  stream  flowing  faster  than  the  surrounding  .  As  the  glacier  moves  toward  the  sea  or  a  body  of  water,  it  extends  outward,  forming  a  large,  finger-like  projection  of  ice.  This  happens  when  the  glacier's  flow  rate    the  surrounding  ice,  causing  the  ice  to  break  off  and  form  an  "ice  tongue".  Over  time,  sections  of  the  ice  tongue  may  ,  creating  icebergs  and  further  shaping  its  structure.  One  well-known  example  is  the  Erebus  Ice  Tongue,  located  on  the    of  Antarctica  near  Mount  Erebus.  This  ice  tongue  extends  from  the  Ross  Ice  Shelf  and  is  influenced  by  both  the  flow  of  the  glacier  and  the  nearby  volcanic  activity  of  Mount  Erebus.  The  Erebus  Ice  Tongue  is  a  significant  feature  in  glaciology  because  it  highlights  the  interaction  between  glacial  dynamics  and  geothermal  heat  from  the  volcano.  The  formation  and  stability  of  ice  tongues  like  Erebus  are  important  for  understanding  sea-level  ,  as  changes  in  the  ice  tongue's  size  or  structure  can  affect  the  flow  of  ice  into  the  ocean.  Studying  these  features  helps  scientists  predict  how  Antarctica's  glaciers  will  respond  to  climate  change  and  their  potential  contribution  to  rising  sea  levels.

Correct answer: ice

Explanation: The word 'ice' fits grammatically as it is a noun that matches the context of the sentence, which discusses the formation of an ice tongue. The surrounding context indicates that the ice stream flows faster than the surrounding material, and 'ice' is the most relevant option here.

Meaning: 'Ice' refers to frozen water, which is the primary substance being discussed in the context of glaciers and ice tongues.

Wrong options:

  • rock: 'Rock' refers to solid mineral material, which does not fit the context of glacial movement as it is not a comparable substance to ice in this scenario.
  • water: 'Water' is a liquid and does not align with the comparison being made, as the ice stream is specifically flowing faster than the surrounding ice.
  • sand: 'Sand' is a granular material that is not relevant to the discussion of glacial formations and does not fit the context of ice movement.
Correct answer: exceeds

Explanation: The verb 'exceeds' is in the present tense and agrees with the subject 'flow rate,' which is singular. This fits grammatically and contextually as it describes the glacier's flow rate surpassing that of the surrounding ice.

Meaning: 'Exceeds' means to go beyond a certain limit or level, indicating that the glacier's flow rate is greater than that of the surrounding ice.

Wrong options:

  • exceed: 'Exceed' is the base form of the verb and does not agree with the singular subject 'flow rate,' making it grammatically incorrect in this context.
  • exceeding: 'Exceeding' is a gerund and does not fit the sentence structure, as it requires a finite verb form to convey the action clearly.
  • exceeded: 'Exceeded' is in the past tense, which does not match the present context of the glacier's ongoing movement.
Correct answer: calve

Explanation: The verb 'calve' is in the base form, which is appropriate here as it follows the modal verb 'may.' This indicates a possibility of the ice tongue breaking off sections to create icebergs.

Meaning: 'Calve' means to give birth to or produce, specifically in this context referring to the breaking off of ice from a glacier or ice tongue.

Wrong options:

  • calves: 'Calves' is the third person singular form and does not fit the structure following 'may,' which requires the base form of the verb.
  • calving: 'Calving' is a gerund and does not fit the sentence structure, as it requires a finite verb form to convey the action clearly.
  • calved: 'Calved' is in the past tense, which does not match the present context of the ongoing process of ice formation.
Correct answer: coast

Explanation: The noun 'coast' is singular and fits grammatically as it refers to the land along the edge of the sea, which is the correct context for describing the location of the Erebus Ice Tongue.

Meaning: 'Coast' refers to the land next to the sea, indicating the specific geographical area where the ice tongue is located.

Wrong options:

  • coasts: 'Coasts' is the plural form and does not fit the singular context of the sentence, which refers to a specific location.
  • coastline: 'Coastline' refers to the outline of a coast and is not appropriate here as it does not match the grammatical structure needed.
  • coastal: 'Coastal' is an adjective and does not fit the noun requirement of the blank, making it grammatically incorrect.
Correct answer: rise

Explanation: The noun 'rise' fits grammatically as it is the subject of the sentence, indicating the increase in sea level. This aligns with the context of discussing changes in ice tongues and their effects.

Meaning: 'Rise' refers to an increase or upward movement, specifically in this context relating to sea levels.

Wrong options:

  • rises: 'Rises' is the third person singular form and does not fit the context of the sentence, which requires a noun.
  • rising: 'Rising' is a gerund and does not fit the sentence structure, as it requires a noun form to convey the subject clearly.
  • raise: 'Raise' is a verb and does not fit the noun requirement of the blank, making it grammatically incorrect.
