The different types of water that make up Earth's water supply are saline water, which includes oceans and seas with high salt content; fresh water, found in rivers, lakes, and groundwater with low salt content; and frozen water, such as glaciers and ice caps. These different types of water play essential roles in the water cycle and are critical for sustaining life on Earth.

Evidence of paleomagnetism can be found in basalt that has cooled from lava. Other evidence is that any rock with magnetic minerals are presents, and sedimentary rocks where minerals form from ion bearing ground water.

The process of pressing sediments together to form solid rock is called compaction. It occurs when layers of sediment accumulate on top of each other, with the weight of the overlying layers causing the sediments to be pressed tightly together.

The atmoshpere is made up of the troposphere, the stratosphere, the mesosphere, and the thermosphere. The atmosphere consists from dry air and water vapor (average 1%). Dry air contains 78% nitrogen, 21% oxygen, 1% other gases (mostly argon 0.9% and carbon dioxide 0.04%). Percentages are by volume.

The energy that causes seawater to form water vapor is heat from the sun. When the sun's energy heats up the surface of the ocean, it causes water molecules to evaporate and rise as water vapor.

Granite, rhyolite, and pegmatite are examples of felsic rocks. These rocks are light in color and have high silica content, making them rich in minerals like quartz and feldspar. Felsic rocks are associated with continental crust and are often found in areas with volcanic activity.

During freezing, water temperature decreases as heat is removed from the water, causing the molecules to slow down and eventually form into a solid state. At the freezing point, the water remains at a constant temperature until it has fully solidified into ice.

Water will evaporate from any source, especially when heat is present. If in a closed container it will just turn to condensation. But if in a lake or stream, It will be absorbed into the clouds.

To keep the earth going, it is essential to focus on sustainable practices such as reducing waste, conserving energy, supporting renewable resources, protecting natural habitats, and promoting biodiversity. It is crucial to make environmentally conscious choices in our daily lives, advocate for policies that prioritize the health of the planet, and educate others on the importance of environmental stewardship.

In 100 million years, the western part of California will likely have moved further northwards due to the ongoing tectonic movement of the Pacific Plate. This movement is part of the natural process of plate tectonics, which shapes the Earth's surface over millions of years.

its clay soil n please refer to the link below u will get aal the info regarding soil structures... http://www.pedosphere.com/volume01/pdf/section_03_02_01.pdf

This study is known as geology. Geologists analyze rocks, minerals, and the various forces that shape the Earth's surface, such as erosion, plate tectonics, and volcanic activity. By studying these materials and processes, geologists can better understand the history and dynamics of our planet.

Clean up is important because it helps maintain a clean and organized environment, which can improve safety, prevent accidents, and promote overall well-being. It also helps to reduce the spread of germs and pests, as well as improve aesthetic appeal.

The tilt of the Earth's axis causes different hemispheres to receive varying amounts of sunlight throughout the year. When one hemisphere is tilted away from the sun, it experiences winter while the other hemisphere is tilted towards the sun and experiences summer. As Earth orbits the sun, the hemispheres switch positions, leading to opposite seasons in the northern and southern halves of the planet.

The ratio of the volume of the Sun to Earth is approximately 1,300,000 times. This means that you could fit about 1.3 million Earths inside the Sun.

This changes the shapes of continents because different parts of the continents converge and diverge at different rates. So the Northern part of a continent could be spreading apart faster than the southern.

There will be a continuous line describing the perimeter of the depression, and along this line will be short spikes extending inwards; indicating that there may be a cliff there. Ordinarily, they will be marked in black, but on a glacier, they will be shown in blue. This convention should be indicated on the legend of the map.

Sunrise is important for various reasons. It marks the beginning of a new day, provides natural light for visibility and productivity, and has been shown to have positive effects on mental health and well-being. Additionally, many cultures and traditions around the world hold sunrise in symbolic regard, signifying renewal and new beginnings.

The Arctic is like a desert in that it has low precipitation levels, with much of the moisture being locked up in ice rather than falling as rain. The Arctic also has extreme temperatures, creating harsh conditions for plant and animal life. Additionally, both deserts and the Arctic have limited vegetation cover and lack of easily accessible water sources.

The steep area between the continental shelf and the ocean floor is called the continental margin. A continental margin is usually composed of a steep continental slope that is followed by the flatter continental rise.

you just have to do 50*12 and that equals 600!

It is not known exactly who the first person was to step foot on Earth as human history and evolution date back millions of years. The first known human ancestors, Homo sapiens, appeared in Africa around 300,000 years ago.

Viewing Earth from space has provided humans with a greater understanding of the planet's fragility and interconnectedness, leading to increased awareness of environmental issues like climate change and deforestation. It has also contributed to advances in technology and scientific research, such as weather forecasting and resource management. Additionally, it has helped foster a sense of unity and cooperation among nations through collaborative space missions and projects.

No, the Sun is much heavier than the Earth. The Sun's mass is about 333,000 times greater than the Earth's mass.

When the ice on a glacier moves it creates groves in the earth.

Water gets into little cracks in rocks, stone, bricks etc, when the water freezes into ice it expands making the crack larger, this process repeats until eventually chunks of rock, brick, stone break away, over hundreds. thousands even millions of years the landscape changes because of this erosion by 'ice'
