Module 7: How the Atmosphere Works – LUOA Questions and Answers Already Passed What are current atmospheric conditions called? Weather Calculate the Kelvin Temperature if the temperature in ° C is equal to 42. 315.15 K Cellular __________ is the process of converting food into usable energy. respiration 80% of the atmosphere's mass is near __________ with 99% being below 20 miles (32 km). sea level __________ is the study of the atmospheric conditions. meteorology Weather is defined as the current __________ conditions. atmospheric Carbon dioxide is necessary for plants to use when they convert solar energy into food, stored as glucose, and this process is called __________. photosynthesis __________ is what protects us from the ultraviolet radiation from the Sun. ozone The __________ layer only goes to about 620 miles (1,000 km). oxygen Describe and explain the process of nitrogen fixation. Please use complete sentences and proper grammar. Since nitrogen is necessary for living things, but most living things cannot get their nitrogen requirements directly from the air we breathe, specialized bacteria converts the nitrogen into usable forms for plants. Nitrogen fixation is when Nitrogen is changed from N2 into a usable form. Above the tropopause is the layer which starts between 6.2 miles to 8.1 miles (10-13 km), depending on the latitude, and is made up primarily of ozone, which is called the __________. stratosphere The __________ is the thickest layer of the atmosphere, is located between the mesosphere and the exosphere, and the top (which is the exosphere) is approximately 500 km from Earth's surface. thermosphere The __________ is the layer of the atmosphere that is closest to the surface of the Earth and is where about 80% of the atmospheric mass is located, as well as where most of the weather occurs. troposphere The __________ is found above the stratosphere, 50 km above the Earth's surface, and is where you find planes and weather balloons stratopause Directly above the stratopause is the __________ which is between 50 and 90 km high and has very little atmospheric ozone, so the temperature begins
