In the lessons

In science lessons, the Moon has many craters made by rocks from space; children model them by dropping marbles into flour. In geography, volcanoes have craters. In stories, a crater shows something huge crashed or exploded. Phrases: «impact crater», «volcanic crater», «craters on the Moon».

Examples

• The Moon's surface is covered in craters. tree →
• We dropped stones into a tray of flour to make craters. tree →
• Smoke rose from the crater of the volcano. tree →
• A meteorite made a huge crater in the desert. tree →
• Bigger stones made deeper craters in our experiment. tree →
• The bomb left a crater in the road. tree →
• Some craters fill with water and become lakes. tree →
• Does the crater of the volcano know that the glowing lava is pouring from it? tree →

Note

Countable: «a crater», «craters». In a science experiment, crater size can be measured (width, depth) and compared with the height or mass of the dropped object. Not to be confused with «creator» (someone who makes things).
