Imagine that you and your friend are at the beach. You have your chairs and umbrella set up in the perfect spot near the water so you can jump in to cool off with ease. A few hours into your stay, the water line has managed to creep up closer and closer to your chairs and your things start to get wet! Your friend points up at the Moon and says it is to blame. What does this mean? Write a response in complete sentences. plz someone help!!!!!!!
Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

What happens when you add pollution to the water?
Can coral survive bleaching?
What is coral?
Answer:
Explanation:
Increasing temp in water makes it start to boil and evaporate into the atmosphere, in terms of climate change it makes it hard for many organisms to survive because they have to adapt quickly to the waters rapidly rising temperature. When you add pollution to water the water would become contaminated and not be able to support life or be fit for human consumption.
Coral cannot survive bleaching because it harms the coral to the point of its destruction.
Coral is an animal that can grow into big reefs that create large ecosystems for many organisms. They are in the ocean. The biggest coral reef is the great barrier reef in Australia.

Climate is different from the weather. Climate is the long term weather condition and weather is short term atmospheric condition. The annual precipitation is report is depicted as graphical data. Transformation of water vapor to liquid droplets in air is called condensation.
What is climate?Climate in a region is the long term weather exists there and which will be characteristic for that region. Weather is forecasted for a day or a particular time, reporting the short term atmospheric condition. Climate of a locality depends on the landscape there, local winds etc.
The annual precipitation report determined by the summation of monthly precipitation data and which in turn obtained by the summation daily precipitation for each month and it is depicted graphically to analyse.
The transformation of water vapor to liquid droplets in the air is called condensation. The gaseous molecules of the water vapor condense together to form the liquid droplets.
