The correct answer is that the H zone becomes narrower.

The H-band refers to the region of the thick filaments, which is not overlaid by the actin (thin filaments). Within the H-zone is a thin M-line, which is formed of cross-connecting components of the cytoskeleton.

At the time of muscle contraction, the A-bands do not vary in their length, whereas the H-zone and the I-bands shorten. This makes the Z-lines come near to each other.

Which statements about the cycle of weathering, erosion, and deposition are true? Check all that apply.
kompoz [17]

The correct statements are-

Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity.

When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface.

Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.

Which causes a sea breeze?
vodka [1.7K]

The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze.

This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land.

Nataly [62]

A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

Explanation:

The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

This phenomenon between the differences in land and water temperature causes land sea breeze to occur.

  • Water has a very high specific heat capacity.
  • This implies it takes more heat to cause a monumental increase in its temperature.
  • It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.

A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.

Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.
