Simile or Metaphor?

The child’s tears were cold raindrops from a tiny cloud.

I am as hungry as a bear recently awakened from hibernation.

The stars are diamonds in the sky.

The sky was the colour of the calm Pacific thousands of miles from land.

My thoughts fluttered from subject to subject like a butterfly visiting flowers in a field.

Like a silent thief, the dog crept into the kitchen.

The snow covered the house like a blanket.

She was a kite, floating above the confusion around her.

My noisy sister was like a buzzing fly.

The water is sparkling like a sky full of stars.

Soft and warm, the bed was an inviting oasis.

The sunshine was like a warm blanket on a cold and rainy night.
