Answer:
A
Explanation:
The Earth rotates on a tilted axis. Since the Earth also moves around the sun, one part of its face will be exposed the sun's light, while the other part will be in darkness.
Because the Earth spins, for a certain number of hours, one face will be exposed to the sun, so that's day. However, after spinning for a while, that face will then be turned away from the sun, and will experience darkness, which is night.
Thus, day and night are caused by the Earth's rotation on its axis.
Hope this helps!
Earth experiences day and night due to its rotation on its axis. When a part of Earth is facing the Sun, it experiences daylight while the part not facing the Sun experiences night. This is different from the Earth's revolution around the Sun, which causes the change of seasons.
The best description of why Earth has day and night is that the Earth rotates on its axis. Imagine the Earth as a spinning top. One full rotation or one complete spin of Earth on its axis is what we understand as a 24-hour day. When a part of the Earth is facing the Sun, it experiences daylight, and when it is not facing the Sun, it experiences night. It's this rotation that gives us the cycle of day and night. This rotation is fundamentally different from the Earth's revolve around the Sun, which takes about 365.24 days and gives us our year.

Answer:
The answer is:B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.
Explanation:
"Eutrophication" is the enrichment of surface waters with nutrients for plants, both nitrogen and phosphorus contribute to eutrophication.
A lake with total concentrations of phosphorus and chlorophyll-a of 10 and 2.5 mg / m3 respectively, can be classified into different eutrophication classes.
The symptoms and effects of eutrophication are as follows:
· Increased production and biomass of phytoplankton, associated algae and macrophytes.
· Production of toxins by certain algae.
· Deoxygenation of water, especially at the end of algal growth situations.
The answer is:B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.

Prominences are indeed a common phenomenon observed in the Sun's atmosphere, specifically in the solar chromosphere and corona.
A prominence is a relatively cooler and denser structure composed of solar gases, primarily hydrogen and helium, that becomes visible as a bright, arch-like or loop-like feature extending from the Sun's surface. Location: Prominences are located above the Sun's visible surface, known as the photosphere, in the outer layers of the solar atmosphere. They are best observed during solar eclipses or through specialized solar telescopes equipped with filters to block out the intense brightness of the Sun's photosphere. Types of Prominences: There are two main types of solar prominences: quiescent prominences and eruptive prominences.
prominences are prominent features seen in the Sun's outer atmosphere, characterized by arch-like structures formed by cooler and denser solar gases. They are manifestations of the Sun's complex magnetic activity and provide valuable insights into solar behavior, contributing to our understanding of solar physics and space weather phenomena.
