Answer:

Astronomers place telescopes above to observe radiation from those parts of the electromagnetic spectrum for which the atmosphere would normally absorb or significantly scatter that radiation. This includes UV, X-ray, gamma ray, and infrared.

A(n) is a bend in a steep narrow bedrock valley. 2. The lowest level to which a stream can erode is called . 3. A(n) is the remn
borishaifa [10]

Answer:

1. Incised meander.

2. Base level.

3. Terrace.

4. Lake

5. Meander.

6. Floodplain.

Explanation:

Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.

Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.

Some of the characteristics of an erosion include the following;

1. An incised meander is a bend in a steep narrow bedrock valley. It avails a river large amount of vertical erosion power and as such enabling a downcut.

2. The lowest level to which a stream can erode is called a base level. Some examples are dam, waterfall, lake, stream, etc.

3. A terrace is the remnant of a former floodplain.

4. Examples of local base level include a stream or a lake.

5. A sweeping bend of a stream which is migrating laterally in a wide, flat valley is called a meander.

6. The flat, broad area surrounding a stream is referred to as a floodplain.

Write the differences between avalanches and GLOF?
Eddi Din [679]

Answer:

An avalanche can be caused by vibrations from an earthquake or in severe conditions loud sounds can disrupt the snow.

GLOF is where a body of water contained by a glacier melts or overflows the glacier.

Explanation:

Avalanches occur in mountainous regions with a thick snow cover while a landslide occurs in sloppy places with loose and muddy soil. ... An avalanche is the movement of large snow volumes. An avalanche can be caused by vibrations from an earthquake or in severe conditions loud sounds can disrupt the snow.

How does energy from the sun affect the motion of molecules in a solid compared to molecules in a gas?
astraxan [27]
<h2>Right answer: Molecules in a solid move slower than in a gas. </h2>

Matter is composed of molecules, which are always motion, however, the speed of this movement will depend on its state:

-If it is a solid, the movement of the molecules at room temperature is <u>very small</u>. This means, the atoms intertwine forming defined narrow crystal structures.

-In the case of liquids, molecules have more movement, however there is still some union between the atoms of the body, although much less intense than in the solids. This can happen if the temperature of a solid increases, it loses form until the crystalline structure disappears, reaching the liquid state.

-In the gases the movement of the molecules is <u>maximum</u>, it can be said that they are in chaos and show little response to gravity. They move so quickly that they are released from each other and are hugely separated from each other.

Now, the radiation coming from the Sun is transformed into kinetic energy causing the movement of the molecules, then this kinetic energy is transformed to thermal energy (heat). Hence, when there is an increase in temperature (due to the increase in kinetic energy) the speed of the vibration of the molecules increases.

However, these changes are not the same in all the states of matter. In the case of the solid state the molecules move slowly compared to the liquid and gaseous state.
