Mark the statements as True (T) or False (F).
1. We live in the troposphere.
2. There are seven main layers of the atmosphere.
3. The lower part of the exosphere is commonly called the ionosphere.
4. All weather changes occur in the stratosphere.
5. The ozone layer is found in the thermosphere.
Answer (2)
Let's go through each statement and determine if they are true or false:
We live in the troposphere.
True (T): The troposphere is the lowest layer of Earth's atmosphere where we live and where weather occurs. It extends from the Earth's surface up to about 8-15 kilometers (5-9 miles) in altitude.
There are seven main layers of the atmosphere.
False (F): The Earth's atmosphere is divided into five main layers. These layers are, from lowest to highest, the Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
The lower part of exosphere is commonly called ionosphere.
False (F): The Ionosphere is not a separate layer but is a part of the Thermosphere and extends partially into the Exosphere. It is characterized by ionized particles and is crucial for radio communication.
All weather changes occur in the stratosphere.
False (F): Weather changes occur in the Troposphere, not the Stratosphere. The Stratosphere is above the Troposphere and contains the ozone layer, which helps absorb and scatter ultraviolet solar radiation.
The ozone layer is found in the thermosphere.
False (F): The Ozone Layer is located in the Stratosphere. It plays a crucial role in protecting the Earth from harmful UV radiation from the sun.
Most statements about the atmosphere are false, except for the first one, which is true. The atmosphere has five main layers, and significant weather occurs in the Troposphere, not in the Stratosphere. The ozone layer is found in the Stratosphere, not the Thermosphere.
