The Greenhouse effect

The greehouse effect is essentian for life.
1. True
2. False
Without the greenhouse effect temperatures will be very
1. low
2. high
The solar radiation that reaches the Earth's surface is
1. reflected by the Earth and lost completely in space.
2. reflected by the Earth and then rebounds at the layer of gases that surround the Earth and heats the atmosphere and the Earth.
The rise in the emission of certain gases causes that
1. more solar radiation stays inside the layer of gases.
2. more solar radiation is able to escape into space.
The rise in the emission of certain gases causes that
1. the layer of gases becomes thicker.
2. the layer of gases becomes thinner.
The final consequence of the greenhouse effect is that
1. temperatures will increase.
2. temperatures will decrease.
What causes the greenhouse effect?
1. The emission of certain gases.
2. The Ozone layer.
