Answer:
The correct answer is cation. See the explanation below, please.
Explanation:
An atom with a net charge, either positive or negative, is called an ion. In the event that an atom loses an electron (or more), that is, it will have more protons than electrons, and its net charge will be positive, it will be called cation. In the opposite direction, if an atom gains electrons, it will have a negative net charge, called anion.
I think the correct answer from the choices listed above is option 2. When the products of a reaction are hotter than the reactants the reaction is endothermic. The change in temperature is a measure of energy difference of the states. Since energy must be conserved, so there must be a source of energy for the system.
When you have the bottom measurement of the triangle (base) and the height of the triangle in the center, you multiply them together and then divide by 2.

The correct answer is - wave erosion.
The sea stack, sea arch, and the sea caves, are all land features that have gradually been formed by the influence of the waves, or rather by the erosion that the waves have caused on them.
The sea stack is a land form very close to the coast, and it is manifested by solitary very steep rocks, or as group of very steep rocks, and they have formed because of the wave and wind erosion.
The sea arch is land form that appears as an opening in a cliff, being formed by the the wave refraction where the focus of waves goes on the sides of a headland.
The sea caves are openings deeper into the crust, where the waves managed to erode the softer rocks, and the water to penetrate deeper inside.
Earth is the only planet in the solar system with an atmosphere that
can sustain life. The blanket of gases not only contains the air that we
breathe but also protects us from the blasts of heat and radiation
emanating from the sun. It warms the planet by day and cools it at
night.
Earth's atmosphere is about 300 miles (480 kilometers) thick, but most
of it is within 10 miles (16 km) the surface. Air pressure decreases
with altitude. At sea level, air pressure is about 14.7 pounds per
square inch (1 kilogram per square centimeter). At 10,000 feet (3 km),
the air pressure is 10 pounds per square inch (0.7 kg per square cm).
There is also less oxygen to breathe.
If it were to be in a different position, life can no longer be alive on Earth.
