1) What does a model of the rock cycle show?
The amount of Earth’s carbon increases.
The amount of Earth’s carbon is constant.
The amount of Earth’s carbon cannot be determined.
-> The amount of Earth’s carbon decreases.
2)What does a wider tree ring indicate, as opposed to a thinner tree ring?
-> It indicates that the weather that year was warm and wet.
It indicates that the weather that year was cold and dry.
It indicates that the weather that year was warm and dry.
It indicates that the weather that year was cold and wet.
3)Select the correct answer from the list
Scientist believe that the (sea levels _ Milankovitch cycles _ low temperatures _ TILT OF EARTHS AXIS) explain why Earth's (low temperature have _ CLIMATE HAS _ sea levels have _ tilt of Earth's axis has) fluctuated between Glacial Periods and Interglacial Periods.
4)How does climate change affect energy in the atmosphere?
Decreased ice causes more energy to be reflected.
Increased ice causes less energy to be reflected
Increased ice causes more energy to be reflected.
-> Decreased ice causes less energy to be reflected.

less water vapor in the atmosphere
more severe storms
-> more water vapor in the atmosphere
less severe storms

There are two other questions that have been attached as photos.

The branch of science which deals with the living organism is called biology. In this branch, we study plants and animals.

Answer no 1)

The correct option is B) The amount of Earth’s carbon is constant.

Explanation:

The rock cycle generally shows the transitions which occur in the three types of rocks present on the Earth which are sedimentary, metamorphic and igneous rocks. The rock cycle shows that the carbon in the rocks might change from one form to another but the amount of carbon remains constant on Earth. It may change from one form to another.

Answer No 2)

The correct option is A) It indicates that the weather that year was warm and wet.

Explanation:

The colour and width of the rings in a tree determine the climate conditions in the past. The tree rings will be wider if the climate condition has been wet and hot in the previous year. On the contrary, the tree rings will be thinner if the climate has been cold and dry in the previous year.

Answer No 3)

Scientist believe that the tilt of the Earth's axis explains why Earth's climate has  fluctuated between Glacial Periods and Interglacial Periods.

Studies have shown that the changes in the Earth's climate arise due to the tilting of the Earth around it's axis. The Earth has a tilt of 23.8 degrees and this tilt causes the different seasons to occurs.

Answer No 4)

The correct option is D) Decreased ice causes less energy to be reflected.

Explanation:

The albedos studies have shown that the ice reflects more energy as compared to liquid water. This means that the nature of ice is to absorb less energy and reflect more. On the contrary, water in the liquid form absorbs more energy and reflects back less. Te climate changes in the past have led to decrease in ice and hence more energy is absorbed as compared to the amount of energy that is reflected back.

Answer No 5)  

The correct option is the concentration of the green house gases.

Explanation:

The Earth receives basic energy from the sun. However, the flow of energy is controlled by many factors such as the green house gases as well as the amount of light which is reflected back. The green house gases causes the temperature in the Earth to rise  and should be a part of the energy flow in the atmosphere.

Answer No 6)

The correct option is more water vapour in atmosphere

The increase in temperature causes more heat due to which water turns into water vapours and is releases into the atmosphere. This causes a rise in the global temperatures along with the emission of the green house gases,. The rise in the temperature of the Earth is a serious threat to the existence of life on Earth.

Answer No 7)

Event that occurred billions of years ago- oxygen building up in earths atmosphere

Event that occurred thousands of years ago- the last ice age

Event occurred decades ago- carbon dioxide levels reach the highest levels of record

Answer No 8)

Ocean acidification evidence will include the following difficult for species to make shells,larger concentration of carbon acid,organisms more prone to illness

Ocean warming incidents will include the following melting glaciers, expansion of ocean volume,difficulty absorbing carbon dioxide

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
