The atmosphere is a mixture of different gases, dust particles, and water vapor. At the Earth’s surface, the gases are mostly nitrogen (78%) and oxygen (21%). The remaining 1% is a mixture of argon, carbon dioxide, and small amounts of other gases.(2 points)

Answer 5

Question 1: True

The atmosphere is indeed a mixture of different gases, dust particles, and water vapor. Nitrogen makes up about 78% of the gases, oxygen makes up about 21%, and the remaining 1% is a mixture of argon, carbon dioxide, and other gases.

Question 2: True
The atmosphere is divided into five layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere. Each layer has its own properties, and there are no definite boundaries between them. The layers gradually blend into each other as altitude increases.

Question 3: False
The lithosphere refers to the rigid outer part of the Earth, including the rocks, soil, and landforms. It does not include living things. The correct definition for the lithosphere is: the solid, outermost layer of the Earth that includes the crust and uppermost part of the mantle.

Question 4: True
The hydrosphere refers to all the water found on, under, or above Earth's surface. This includes oceans, lakes, rivers, groundwater, and even water vapor in the atmosphere.

Question 5: True
The exosphere is the outer layer of the atmosphere that extends from about 700 km above Earth's surface to outer space. It is the highest layer of the atmosphere and contains very thin air molecules that gradually dissipate into space.

Answer 6

Question 1:

To answer this question, we can observe that the statement is true. The atmosphere is indeed a mixture of different gases, dust particles, and water vapor. By looking at the Earth's surface, we can see that nitrogen makes up about 78% of the gases in the atmosphere, while oxygen comprises approximately 21%. The remaining 1% consists of a mixture of argon, carbon dioxide, and small amounts of other gases.

Question 2:
To determine if the statement is true or false, we can recall the layers of the atmosphere and their characteristics. The atmosphere is indeed divided into five layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has its distinct properties and as altitude increases, one layer gradually blends into the next. Therefore, the statement is true.

Question 3:
To assess the accuracy of the statement, we need to understand what the lithosphere represents. The lithosphere refers to the solid outer shell of the Earth, including the crust and uppermost part of the mantle. It does not encompass all the living things on Earth. Therefore, the statement is false.

Question 4:
To determine the truthfulness of the statement, we must understand the meaning of the word "hydrosphere." The hydrosphere is the entire water component on, under, and above the Earth's surface, including oceans, lakes, rivers, groundwater, and water vapor in the atmosphere. Therefore, the statement is true.

Question 5:
To verify if the statement is accurate, we need to comprehend the definition of the exosphere. The exosphere is the outermost layer of the Earth's atmosphere, extending from approximately 700 km to outer space. Thus, the statement is true.
