AveGali [126]3 years ago

Answer:

B

Explanation:

"Energy is generated in a red dwarf in the same way that it is in the Sun, namely through the fusion of hydrogen into helium. ... So long is the process, in fact, that the lifespan of a red dwarf can be far longer than the expected age of the universe, thought to be about 14 billion years."

How does undestanding the water cycle help us examine the cause of sea level rise?
coldgirl [10]

Answer:

Water cycle is also known as the hydrological cycle. It involves the water in water bodies such as ocean, river, lakes etc being heated up by the sun and then evaporations into the atmosphere. The evaporated water then condenses and falls back as rain into the water bodies.

The water body is always low during summer due to the water being heated and evaporated into the atmosphere and high during spring/winter due to rainfall and less evaporation.

What is the difference between the life cycle of ferns and the life cycle of humans?
Bond [772]
Ferns make their own food. They grow and reproduce using spores instead of things like seeds. Humans on the other hand have to ingest food from their surrounding and when mature reproduce sexually. They can also choose if they want to reproduce or not while ferns don't have that option. Sexual reproduction is based on inseminating and egg cell, while ferns don't worry about this because the spores just fall on the ground.

1. Why is California at hingher for earthquakes than North Dakota
Pani-rosa [81]

Answer:

because California is located on the San Andreas Fault

Explanation:

California is one of the states that have higher seismic activity because it lies on an individual fault known as the San Andreas Fault. Faults are regions where two tectonic plates are moving with respect to one another, thereby they are prone to suffer earthquakes. The San Andreas Fault is a continental fault that extends approximately 800 miles (1,200 kilometers) through the US state. Conversely, earthquakes in North Dakota are uncommon because this state is located in the middle of a tectonic plate. The last earthquake in North Dakota had a magnitude of 3.3 (Richter Scale) and it happened almost 10 years ago (2012), in Williston.
