• boggy soil in summer

• ground deeply frozen deep down

• covered in ice all year

Why was Britain joined to the rest of Europe during the ice age?

• Sea levels were lower in the north because there was less rainfall in the cold climate.

• Sea levels were lower because water was trapped in ice on land.

• Sea levels were higher because of all the ice in the oceans.

• Sea levels were lower because colder water is less dense than warm water.

Why was Britain separated from the rest of Europe again?

• Europe moved further away from Britain as Earth cooled.

• Britain moved further away from Europe as Earth's surface warmed.

• As the planet cooled, sea water expanded and sea levels rose.

• As the planet warmed up, ice melted and sea levels rose.
