TEKS 7.9A - Characteristics for life

Proximity to the Sun means...

• A proximity warning is given to an astronaut when the oxygen level in the spacesuit drops below 10 pounds/square inch of atmosphere

• The intensity of the Sun's radiation on Earth

• How close an object in our solar system is to the Sun

• none of theses

Why is the Sun important to life on Earth?

• The Sun's radiant energy is converted to food by plants in a process called photosynthesis

• The Sun's radiant energy is converted into liquid water

• Radiant energy from the Sun is absorbed and released in a delicate balance for life to exist.

• none of these

Why is liquid water important for life to exist?

• Other life forms get thirsty just like humans

• Liquid water is important for rain to fall and wash the pollution from the surface of the planet

• none of these

• delivery mechanism, dissolving essential nutrients and delivering them to cells.

The atmosphere is important to life on Earth because...

• The atmosphere keeps thunderstorms from becoming too large and causing catastrophic damage to Earth

• blocks the Sun's dangerous radiation and traps heat making Earth a comfortable temperature

• The atmosphere traps cold air just above the surface and without this cold air we would not receive the rain that we needed.

• none of these
